Nurses' perception of the impact of professional development sessions on their pre-hospital clinical practice with trauma victims

Background

Continuing education is important for the quality of clinical practice because it complements it and focuses primarily on producing qualified pre-hospital nurses with operationally defined competence in nursing standards. The objective of this study was to assess pre-hospital nurses' opinion of the impact of professional development sessions on their clinical practice.

Method

A descriptive and quantitative study was carried out involving Portuguese pre-hospital nurses. Six professional development sessions were presented in 2020 to pre-hospital registered nurses in four of Portugal's main cities. To collect the data, at the end of each session, we apply a questionnaire designed specifically for this study. This data collection instrument consists of 11 questions, six designed to evaluate the session and five designed to evaluate the trainer responsible for the session. A five-point Likert scale was used for each question, where 1 corresponds to very dissatisfied and 5 to extremely satisfied.

Results

Two hundred and two nurses, which represents 55% of all Portuguese pre-hospital nurses, took part in the assessment of the professional development sessions. The nurses were from the Northern region of Portugal (51%; n = 102), the Centre region (29%; n = 59) and the Southern region of Portugal (20%; n = 41). Nurses found the session extremely satisfactory. All the assessment scores ranged between 4.4 and 4.7 points, on a scale of 1 to 5. 76.2% of the participants considered that the knowledge acquired could have a major impact [score = 5] on their future clinical practice. The majority of pre-hospital nurses (96.5%) felt that the session could have a major impact [score = 5; 76.2%, n = 154] or a very important impact [score = 4; 20.3%, n = 41] on their clinical practice.

Conclusion

The professional development sessions provide pre-hospital nurses with the latest research findings and the majority of nurses considered that the training had a huge impact on their clinical practice. However, it is important that future research aims to explore the cause-effect relationship between training and improved clinical practice.

The relationship between acute pain and other types of suffering in pre-hospital trauma victims: An observational study

BACKGROUND

Acute pain is an important complaint reported by trauma victims, however, the relationship between it and other types of discomfort, such as discomfort caused by cold, discomfort caused by immobilization, and psychological distress such as fear, anxiety, and sadness is limitedly studied and documented.

AIM

To assess the relationship between acute trauma pain and other types of suffering in pre-hospital trauma victims.

METHODS

This is a prospective multicentre cohort study conducted in Immediate Life Support Ambulances in Portugal. All adult trauma victims with a mechanism of blunt and penetrating injuries, falls, road accidents and explosions, were included.

RESULTS

605 trauma victims were included, mainly male, with a mean age of 53.4 years. Before the intervention of the rescue teams, 90.5 % of the victims reported some level of pain, 39.0 % reported discomfort caused by cold, while 15.7 % felt fear, 8.4 % sadness, 49.8 % anxiety and 4.5 % apathy. Victims with high discomfort caused by cold tend to have higher pain levels. Significantly higher pain intensity were observed in victims with fear and anxiety. Univariate and multivariate analysis indicates that immobilization is associated with increased pain levels.

CONCLUSIONS

There is a statistically significant relationship between acute trauma pain, anxiety, fear, cold and immobilization.

The REWRITE Study - REal-WoRld effectIveness of TrifluridinE/tipiracil in Patients with Previously Treated Metastatic Colorectal Cancer

AIMS

In the pivotal RECOURSE trial, trifluridine/tipiracil improved survival outcomes in refractory metastatic colorectal cancer (mCRC), while demonstrating an acceptable toxicity profile. Routine clinical practice evidence is important to support the ongoing value of recently approved medicines. Our objective was to assess the utilisation patterns and real-world effectiveness of trifluridine/tipiracil in previously treated mCRC patients.

MATERIALS AND METHODS

This was a retrospective observational study including consecutive patients who started trifluridine/tipiracil between 1 April 2018 and 30 September 2019 in the medical oncology departments of three major public hospitals in Portugal. The primary outcome measure was overall survival. Associations between overall survival and patient and tumour characteristics were assessed using multivariate Cox regression analyses.

RESULTS

In total, 111 patients were included in the study, with a mean age of 64 years. From these, 45.9% received two prior lines of treatment, 47.8% had three or more previous lines of treatment and 83.6% had Eastern Cooperative Oncology Group (ECOG) performance status 0-1 at baseline. The median duration of trifluridine/tipiracil treatment was 3.7 cycles (95% confidence interval 3.4-4.1). Most patients (80.4%) remained on their planned dose throughout the trifluridine/tipiracil treatment period, fulfilling 100% relative dose intensity. The median overall survival in the total study cohort was 7.9 months (95% confidence interval 6.4-9.8) and the median progression-free survival was 3.4 months (95% confidence interval 3.2-3.9). The median overall survival was significantly higher in patients with a normal serum lactate dehydrogenase (LDH) level (median overall survival 11.2 months for [135, 205] IU/l LDH [95% confidence interval 8.2-NR] and 13.6 months for [205, 251] IU/l LDH [95% confidence interval 8.2-NR]) and in better fitted (ECOG = 0-1) patients (median overall survival 8.0 months; 95% confidence interval 6.7-10.0). The median time to worsening performance status was 6.2 months (95% confidence interval 5.0-8.0). Treatment discontinuation due to adverse events was low (3.1%).

CONCLUSION

Our study confirms the effectiveness of trifluridine/tipiracil in real-life mCRC patients. Overall survival and progression-free survival outcomes are consistent with the efficacy profile reported in the earlier randomised RECOURSE clinical trial. Like other real-world studies, we found no additional safety concerns in the use of trifluridine/tipiracil.

Prehospital interventions to reduce discomfort caused by immobilization in adult trauma victims: a scoping review protocol

OBJECTIVE

The objective of this review is to identify the level of discomfort caused by immobilization as reported by trauma victims, and to map all the interventions in the prehospital context where they have been implemented and evaluated in order to reduce discomfort in adult victims of trauma.

INTRODUCTION

Immobilization is a cause of discomfort for trauma victims, which has important implications for the deterioration of vital signs and quality of life. However, discomfort caused by immobilization remains an under-explored topic by the scientific community.

INCLUSION CRITERIA

This scoping review will consider studies of adult victims of trauma, aged 18 years or over, in prehospital emergency care. Studies that focus on interventions designed to reduce immobilization discomfort, implemented and evaluated by health professionals, of any form, duration, frequency, and dose will be considered.

METHODS

An initial search of PubMed and CINAHL will be undertaken, followed by a second search for published and unpublished studies without time restrictions, in major health care-related electronic databases. Studies in English, French, Spanish, and Portuguese will be included. Data extraction will be performed independently by 2 reviewers in a tabular format and will include details about the level of discomfort, interventions, populations, study methods, and outcomes of interest. A narrative synthesis will accompany the results and will describe how they relate to the review objectives.

Impact of emergent coronary angiography after out-of-the-hospital cardiac arrest without ST-segment elevation - a systematic review and meta-analysis

INTRODUCTION

Coronary artery disease is a leading cause of out-of-the-hospital cardiac arrest (OHCA). However, there is no consensus on whether OHCA patients without ST-segment elevation (STE) benefit from emergent (ie < 2 h) coronary angiography (CAG). Our aim was to assess the impact of emergent CAG in no-STE OHCA patients.

METHODS

We performed a systematic review and meta-analysis by searching the MEDLINE, Cochrane, Scopus, CINAHL and JBI databases for randomized controlled trials (RCTs) comparing emergent CAG versus standard of care (ie CAG >2 h after OHCA or not performed) in no-STE OHCA patients of presumed cardiac aetiology. The primary outcome was short term survival. Secondary outcomes included survival with good neurological outcome, mid-term survival, left ventricle ejection fraction (LVEF), acute kidney injury (AKI) and renal replacement therapy (RRT), ventricular arrhythmias and major bleeding during hospital stay.

RESULTS

Seven RCTs met the inclusion and exclusion criteria and were included; one was included only in the analysis of mid-term survival and another in the LVEF analysis. Five studies (1278 patients, 643 with early CAG and 635 with no early CAG) were included in the analysis of the primary endpoint. The groups were balanced for all baseline characteristics but previous PCI, which was more frequent in the standard of care groups. There were no significant differences between groups for short-term survival (57 vs 61%; OR0.85, 95% CI0.68-1.07; I² = 0%). There were also no differences for any of the secondary endpoints.

CONCLUSION

Routine emergent CAG did not improve survival in comatose survivors of OHCA with shockable rhythm and no-STE.

Neurodevelopmental disorders and gender dysphoria: a fertile relationship?

Introduction

Development of gender identity is a complicated process. During this process it is thought that many factors play a role. Gender dysphoria is a condition where there is a mismatch between the assigned gender at birth and gender identity. Although scarce, literature shows that compared to cisgender individuals, transgender and gender-diverse individuals have higher rates of autism, other neurodevelopmental and psychiatric diagnoses.

Objectives

To describe posible relations and overlap between gender dysphoria and neurodevelopmental disorders.

Methods

Literature search in Pubmed and other similar platforms. Articles considered relevant under this theme were included.

Results

Autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD) can compromise health and may be more prevalent amongst individuals with gender dysphoria (GD). Symptoms such as attention difficulties, deficits in communication and social skills, obsessional interests, and stereotyped behaviour can significantly impact assessment of GD and the appropriate clinical care. With some overlapping symptoms, the potential for misdiagnosis is possible. Data about prevalence of this conditions in transgender community is of low quality, but ASD is more prevalent, ranging from 6-26%.

Conclusions

Studies demosntrate that neurodevelopmental disorders and other psychiatric conditions are more common in transgender and gender-diverse individuals. It is important that future studies focus on exploring the mental health outcomes of neurodevelopmental-trans individuals.

STOP-BANG QUESTIONNAIRE - AN EASY TOOL FOR IDENTIFYING OBSTRUCTIVE SLEEP APNEA SYNDROME IN PATIENTS WITH TYPE 2 DIABETES MELLITUS

BACKGROUND

Patients with type 2 diabetes mellitus (T2DM) have a higher risk of developing obstructive sleep apnea (OSA) compared to the general population. Our study aims to analyze the usefulness of the STOP-BANG score, tool which was not yet validated in patients with diabetets, as a tool that estimates the severity of OSA, in patients with T2DM.

METHODS

120 patients, who answered the STOP-BANG questionnaire and underwent polysomnography, were included in the study. The patients were divided into 3 groups, depending on the severity of OSA, defined by the apnea/hypopnea index (AHI).

RESULTS

A significant percentage of participants (42.1%) had a severe form of OSA (AHI ≥30) and a high percentage of subjects had a STOP-BANG score ≥5 (58.7%), equivalent to a severe form of the disease. The STOP-BANG score increased proportionally with AHI (p<0.001). The area under the ROC curve for the STOP-Bang score indicated an optimal cut-off value of 4.5, with a sensitivity of 88.2% and a specificity of 62.9% (p <0.001), STOP-BANG score ≥5 being an independent predictor for severe OSA in patients with T2DM.

CONCLUSIONS

The STOP-BANG score can be used in patients with diabetes to detect severe OSA in order to establish appropriate therapeutic measures.

Third generation cognitive-behavioral therapies and genital pain

Introduction

Genital pain is a heterogeneous chronic pain condition and the relationship between biological, psychological and social factors sets a complex clinical challenge. The importance of negative thoughts and emotions has opened up an opportunity for the role of third generation cognitive-behavioral therapies (CBT). While the majority of evidence revolves around female sexual desire and arousal problems, research on genital pain disorders is beginning to take shape.

Objectives

To review the evidence of third generation CBT on genital pain disorder.

Methods

Review of literature using the Pubmed platform.

Results

We identified 21 publications. Evidence shows that mindfulness-based CBT (MbCBT) improves reduction of fear linked to sexual activity, pain acceptance, catastrophizing and decentering. MbCBT shows significant improvements on secondary outcomes (overall sexual function, sexual satisfaction, depression and anxiety) while reduction of genital pain has yielded contradictory results. Acceptance and commitment therapy (ACT) has been studied for chronic pain disorders with improvements on pain acceptance, psychological flexibility, anxiety, depression and functioning. Compassion-focused therapy (CFT) has yielded favorable results on pain distress and intensity, self-efficacy, self-acceptance, anxiety and depression. Self-compassion may be a promising protective factor in genital pain. Both ACT and CFT have not yet been studied specifically for genital pain.

Conclusions

Third generation CBT are most commonly used for depressive, anxiety and chronic pain disorders which signals the logical role that these interventions may have in genital pain. While MbCBT has started to present favorable results in treating genital pain (as well other sexual problems), ACT and CFT require more research.

Revisiting hysterical psychosis: A case report

Introduction

Holiender and Hirsch defined hysterical psychosis in 1964 and, while hysteria has a contemporary equivalent in somatoform/dissociation disorder, hysterical psychosis remains set adrift in the nosological understanding of psychiatric disorders.

Objectives

To present a case report of a hysterical psychosis and to review this nosological construct.

Methods

Clinical interview, consultation of clinical records and review of literature using the Pubmed platform.

Results

The authors present a case of a 38 year-old woman, admitted in a psychiatric emergency department for bizarre behavior, restlessness, auditory (pseudo)hallucinations and emotional lability, starting 1 week after a personal development retreat. This is the second episode of this nature, the first being a 15-day hospitalization 7 years ago, with rapid stabilization, extensive examination and restitium ad integrum. The patient initiated Olanzapine and was referred to an outpatient clinic, with rapid stabilization and restitium ad integrum throughout follow-up. Given the episode and patient characteristics, a hysterical psychosis diagnosis may be accurate, taking into account the acute onset and course, the pleomorphic nature of symptoms and the presence of a disturbing life event. The authors propose reviewing the concept of hysterical psychosis regarding its clinical implications and debating its therapeutic and prognostic utility.

Conclusions

Hysterical psychosis may not be a mere historic footnote and encompasses an entity with distinctive diagnostic, prognostic and therapeutic characteristics. While its etiology may not be understood, its clinical implications ensure the need for future research.

Non-pharmacological interventions for acute pain management in adult trauma victims: a scoping review

OBJECTIVE

This scoping review aimed to map non-pharmacological interventions to reduce acute pain in adult trauma victims.

INTRODUCTION

Acute pain is a consequence of a pathological or traumatic event, and a result of invasive or non-invasive health care procedures. Acute trauma pain, as well as its treatment, is one of the least-studied areas of acute pain. Although non-pharmacological interventions are responsible for pain relief among a significant number of patients, only a small percentage of patients receive non-pharmacological interventions.

INCLUSION CRITERIA

This scoping review considered all studies conducted on adult victims of trauma, aged 18 years or over, in pre-hospital emergency care, emergency rooms, and trauma-center settings. Studies were considered if they focused on non-pharmacological interventions designed to reduce acute pain, and were implemented and evaluated by health professionals. Non-pharmacological interventions of any type, duration, frequency, and intensity were considered.

METHODS

A comprehensive search strategy across 11 bibliometric databases and gray literature sources was developed. Full texts of selected citations were assessed in detail for eligibility by two independent reviewers. No other relevant studies were identified by searching the references of the included articles. Data extraction was performed independently by two reviewers using an instrument previously developed, and those reviewers were later responsible for its validation. Findings were then extracted directly into tables that are accompanied by a narrative summary to show how they relate to the objectives of the review conducted.

RESULTS

This scoping review included nine studies: two retrospective cohort studies, five randomized controlled trials, one case report, and one literature review for five different countries. Non-pharmacological interventions identified and administered to trauma victims in pre-hospital settings, emergency services, and trauma centers were as follows: acupressure, auricular acupressure, auricular acupuncture, transcutaneous electrical nerve stimulation, repositioning, use of pressure relief devices, massage, heat therapy, music therapy, relaxation therapy, immobilization, ice therapy, compression, elevation, and bandage. Non-pharmacological interventions were mainly developed by nurses, physicians, and paramedics. They were, in most studies, poorly described in terms of their efficacy and were mostly reported in minor traumas, such as simple fractures or small wounds.

CONCLUSIONS

Currently, there is no consensus for the implementation of non-pharmacological interventions in the treatment of acute trauma pain. Their application is primarily used for minor traumas, and their potential for the treatment of major traumas is yet unknown. No studies on the use of non-pharmacological interventions aimed at reducing the impact of traumatic adverse environments were identified. Further investigation on the effects of these interventions should be encouraged so that robust decisions and recommendations can be made.

Looking beyond electroconvulsive therapy: A case report

Introduction

Electroconvulsive therapy (ECT) is considered a gold-standart treatment of severe and treatment-resistant depression. Lack of response to ECT often causes distress in psychiatrists regarding the next therapeutic decisions.

Objectives

To present a case report of a patient with psychotic depression with partial response to ECT.

Methods

Clinical interviews and review of literature using the Pubmed platform.

Results

The authors present a case of a 60 year-old woman admitted for severe depressive episode with psychotic symptoms. Due to lack of response to multiple antidepressive and antipsychotic treatments, 15 sessions of ECT were performed with improvement of behavioral and psychotic symptoms. However, endogenous depressive symptoms with functional impairment persisted. It was then initiated Bupropion 300mg/day resulting in vast improvements on drive, energy and activity levels with restored functionality. Previously to ECT, Bupropion was not considered a valid option due to the psychomotor restlessness that was present. This case exposes the limitations of ECT and the therapeutic conundrums that arise when there is partial response. The symptoms expressed in the patient after ECT course correlate with deficits in noradrenergic and dopaminergic pathways that are involved in endogenous depression. The use of Bupropion, with its effect on noradrenaline and dopamine receptors, may offer a therapeutic lifeline in these cases.

Conclusions

ECT still stands as a gold-standart for severe depressive disorder, especially when several psychopharmacological therapies have failed. In cases of partial response to ECT, the neurobiological correlates of clinical presentation can guide the therapeutic management towards improved outcomes.

Immunotherapy and psychosis: It there a risk?

Introduction

Over the past decades, immunotherapy treatments have been a revolution to many chronic diseases with encouraging results in clinical outcomes and quality of life. The use of monoclonal antibodies has yielded a great variability in terms of clinical efficacy and tolerability although it’s believed the incidence of psychotic symptoms is low (0,1-0,4%).

Objectives

To review the effects of monoclonal antibodies on psychosis.

Methods

Review of literature using PubMed database. A total of 16 studies were included.

Results

The targeted molecules by monoclonal antibodies may determine the risk of psychosis. While those who target TNF-alfa seem to have a reduced risk of psychosis (such as Infliximab, Adalimumab, Certolizumab and Golimumab), monoclonal antibodies who modulate lymphocytes may have a greater risk of psychosis namely Natalizumab, Belimumab, Basiliximab and Daclizumab, which seems to correlate to evidence of alterations in lymphocyte subsets in groups of patients with first psychotic episode and schizophrenia. Some seem to have positive correlation with psychosis namely monoclonal antibodies who have a supressing effect on the immune system, especially those who target adaptative immunity and those who are used in autoimmune diseases (vs oncologic conditions). It is unknown if delusions prevail over hallucinations or vice-versa. Despite the paucity of evidence, these findings corroborate the variability regarding the psychiatric effects of immunotherapy.

Conclusions

The available literature reports a low prevalence of psychotic symptoms associated with the use of monoclonal antibodies but it highlights the importance in knowing the immune mechanisms involved in psychotic disorders. Greater research is needed to correctly assess that risk.

Prehospital interventions to prevent hypothermia in trauma patients: a scoping review

Objective: The aim of this review is to map the prehospital rewarming measures used to prevent hypothermia among trauma victims. Background: Hypothermia is responsible for an increase of the mortality and morbidity in trauma victims and its recognition and early treatment are crucial for the victim’s haemodynamic stabilisation. Prehospital interventions are particularly important, especially those that target bleeding control, haemodynamic stability, and safe body temperature. Registered nurses may be pivotal to prevention and minimisation of the dangerous effects of hypothermia. Study design and methods: A scoping review was used to identify articles from several online databases from 2010 to 2018. Studies in English, Spanish, and Portuguese were included. Two reviewers performed data extractions independently. Results: Seven studies were considered eligible for this review: two quantitative research studies, one qualitative research study, and four literature reviews. Rewarming measures can be divided into two main groups: passive rewarming, which includes the use of blankets, positioning the response unit to act as a windbreak, removing the patients’ wet clothes, drying the patient’s body, and increasing the ambient temperature; and active rewarming which includes the use of heating pads, heated oxygen, warmed intravenous fluids, peritoneal irrigation, arteriovenous rewarming, and haemodialysis. Discussion: Active measures reported by the included studies were always used as a complement to the passive measures. Active rewarming produced an increase in core temperature, and passive rewarming was responsible for intrinsic heat-generating mechanisms that will counteract heat loss. Patients receiving passive warming in addition to active warming measures presented a statistically significant increase in body core temperature as well as an improvement in the discomfort caused by cold. Conclusion: Rewarming measures seem to be essential for the prevention of hypothermia and to minimise the discomfort felt by the patient. In many countries registered nurses can play important roles in the prehospital context of trauma victim’s assistance. Greater understanding of these roles is necessary to the development of better practices.

Non-pharmacological interventions for pain management in adult victims of trauma: a scoping review protocol

OBJECTIVE

This scoping review aims to map non-pharmacological interventions for reducing acute pain for adult victims of trauma.

INTRODUCTION

Acute pain, as a consequence of either a pathological or traumatic event or even due to invasive and non-invasive healthcare procedures, is highly prevalent in critically ill patients. However, specific acute pain as a direct consequence of trauma is one of the least studied areas of acute pain.

INCLUSION CRITERIA

This scoping review will consider studies on adult victims of trauma, aged 18 years or over, in prehospital emergency care, emergency departments and trauma centers. All studies that focus on non-pharmacological interventions designed to reduce acute pain, implemented and evaluated by health professionals in any form, duration, frequency and intensity, will be considered.

METHODS

An initial search of PubMed and CINAHL will be undertaken, followed by a second search for published and unpublished studies from 2000 to the present in major healthcare related electronic databases. Studies in English, French, Spanish and Portuguese will be included. Data extraction will be performed independently by two reviewers in tabular form and include details about the interventions, populations, study methods and outcomes of interest. A narrative synthesis will accompany the results and will describe how they relate to the review objectives.

Early Interaction of Alternaria infectoria Conidia with Macrophages

Fungi of the genus Alternaria are ubiquitous indoor and outdoor airborne agents, and individuals are daily exposed to their spores. Although its importance in human infections and, particularly in respiratory allergies, there are no studies of how Alternaria spp. spores interact with host cells. Our aim was to study the early interaction of Alternaria infectoria spores with macrophages, the first line of immune defense. RAW 264.7 macrophages were infected with A. infectoria conidia, and the internalization and viability of conidia once inside the macrophages were quantified during the first 6 h of interaction. Live cell imaging was used to study the dynamics of this interaction. TNF-α production was quantified by relative gene expression, and the concentration of other cytokines (IL-1α, IL-1β, IL-6, IL-4, IL-10, IL-17, GM-CSF and INF-γ) and a chemokine, MIP-1α, was quantified by ELISA. Conidia were rapidly internalized by macrophages, with approximately half internalized after 30 min of interaction. During the first 6 h of interaction, macrophages retained the ability to mitotically divide while containing internalized conidia. The classical macrophage-activated morphology was absent in macrophages infected with conidia, and TNF-α and other cytokines and chemokines failed to be produced. Thus, macrophages are able to efficiently phagocyte A. infectoria conidia, but, during the first 6 h, no effective antifungal response is triggered, therefore promoting the residence of these fungal conidia inside the macrophages.

Selection of plant species for permanent ground cover in vineyards: Looking for an agronomic and environmental optimum

The installation of a permanent ground cover in vineyards offers numerous agronomic (soil protection, soil fertility) and environmental (reduced leaching of nutrients and of plant protection products, reduced use of herbicides, biodiversity) benefits. Nevertheless, such ground covers are not always free of drawbacks (competition for water and nitrogen, increased risk of frost, management). For the growers, the challenge is to manage the green ground covers in such a way as to preserve their advantages while limiting these drawbacks. Among the tools available to the winegrower is the sowing of a seed mixture composed of selected species: a choice depending of the soil and climatic conditions of the parcel, but also of the different, and sometime contradictory, objectives of the grower. This paper lists the agronomic and environmental issues addressed by the installation of a permanent ground cover in vineyards. It describes two concrete situations – ground cover for vineyards integrated in agro-ecological networks and green cover on the row of vines (as alternative to glyphosate) – for which, according to the objectives and the impacts, a choice of plant species is proposed. At last, it presents the trials now carried out to validate and optimize those selections, as well as the first observations and results gathered to date.

LONG-TERM IMPROVEMENT OF GLUCOSE HOMEOSTASIS AND BODY COMPOSITION IN PATIENTS UNDERGOING LAPAROSCOPIC SLEEVE GASTRECTOMY

CONTEXT

Laparoscopic sleeve gastrectomy (SG) has gained popularity as a metabolic procedure, but its long-term effectiveness for Romanian patients remains unclear.

OBJECTIVES

To assess the long-term efficacy of SG for Romanian patients and to evaluate the differences between 5 years and 1 year follow-up.

DESIGN

A longitudinal, prospective analysis of collected data from 68 patients undergoing SG between 2009 and 2014 was performed. Long-term outcomes at 5 years were analyzed in terms of total weight loss (%TWL), excess weight loss (%EWL), body composition and glucose homeostasis.

SUBJECTS AND METHODS

All patients meeting the standard criteria for SG before inclusion were prospectively enrolled in the study. Of the 68 patients, eight were lost to follow-up, therefore, 60 patients (41.7±12.5 years, baseline body mass index [BMI] 44.6±9.9Kg/m2) were analyzed.

RESULTS

The BMI decreased at 12 months with 30.7% from the preoperative BMI (p<0.001) and subsequently stabilized at 5 years.TWL and EWL were 30.6% and 83.1%, respectively at 1 year, with a slightly increase at 5 years.Therapeutic success rate (%EWL≥50) and diabetes remission rate (Buchwald criteria) were 93.3% and respectively 63.6% at 5 years. Insulin sensitivity index and metabolic clearance rate of glucose increased with 92.5% and 60.1% respectively, in the third month from baseline (p<0.001), while estimated second phase of insulin secretion decreased with 7.9% in the first month postoperatively (p=0.04), remaining stable afterwards.

CONCLUSIONS

SG was effective in terms of %EWL, body composition and glucose homeostasis improvement for Romanian patients, the outcomes stabilizing after 1 year follow-up.

CARDIOVASCULAR RISK ASSESSMENT IN THE ADULT (AGED 40-79 YEARS) ROMANIAN POPULATION

Atherosclerotic Cardiovascular Diseases are the leading cause of death worldwide.

Aim

To estimate the prevalence of cardiovascular risk (CVR) categories in the adult population (aged 40-79 years) of Romania.

Design

The present study was part of the epidemiological, cross-sectional PREDATORR study (PREvalence of DiAbeTes mellitus, prediabetes, overweight, Obesity, dyslipidemia, hyperuricemia and chronic kidney disease in Romania).

Subjects and Methods

Exclusion criteria: age <40/or>79 years old and diagnosis of ischemic vascular disease. The CVR was evaluated using charts developed by the World Health Organization/ International Society of Hypertension (WHO/ISH) available for Europe B (epidemiological sub-region where Romania was included). The CVR was divided into 5 categories: <10%, 10-20%, 20-30%, 30-40%, > 40%.

Results

A total of 1631 subjects (57.0±10.7 years, 45.1% males) were included in the present study.The age and sex-adjusted prevalence of CVR >40% was 2.9% (95%CI 2.8-3.1%), CVR 30-40% was 1.85% (95%CI 1.8-1.9%), CVR 20-30% was 5.8% (95%CI 5.6-6.0%) and 13.0% (95%CI 12.8-13.3%) of the adult Romanian population has a 10-20% CVR, these CVR categories being more frequent in male and older age. Diabetes, overweight/obesity and smoking were associated with high CVR categories.

Conclusion

Romania is one of the countries with high CVR, requiring CVD prevention measures.

Hypersensitivity to antiretroviral drugs

Summary

Background. Antiretroviral therapy (ART) may be responsible for hypersensitivity reactions varying in severity, clinical manifestations and frequency. Case report. We report the case of a 47-year-old woman with HIV infection who developed a delayed mucocutaneous reaction after treatment with ART. Hypersensitivty reaction (HR) to emtricitabine and tenofovir was considered probable based on positive patch tests (PT) and hypersensitivity reaction to nevirapine was confirmed by drug provocation test. Discussion. The diagnosis of HR to ART remains a diagnostic challenge, partly due to unknown mechanism and the absence of validated diagnostic tools. Patch testing may represent a useful method for confirming hypersensitivity. Further investigation in this area is required, so that successful management strategies can be offered, preventing loss of potent and viable antiretroviral agents.

Prevalence of Staphylococcus aureus from nares and hands on health care professionals in a Portuguese Hospital

AIMS

The main goal was to estimate the prevalence of methicillin-resistant Staphylococcus aureus on hands and in nose of health care professionals.

METHODS AND RESULTS

Detection of Staph. aureus on hands or in the nose of 169 individuals was performed. Nasal and hand carriage was found in 39·6 and in 8·9% respectively. About 17·2% of the individuals were carriers of methicillin-resistant Staph. aureus (MRSA) in the nose and 4·7% on hands. The majority of nasal MRSA were resistant to β-lactams, erythromycin and ciprofloxacin. All nasal MRSA were SCCmec type IV and Panton-Valentine leukocidin (PVL) negative. One MRSA isolated from hand was SCCmec type V. About 75·6% of MRSA isolates presented the same or closely related restriction patterns. Sixty per cent of Staph. aureus from hands and from noses from the same individual were the same strain.

CONCLUSIONS

MRSA nasal carriage was high considering healthy health care professionals but in accordance with high level of MRSA infection in Portugal. Isolates recovered in this study seemed to be different from major clones previously isolated in other Portuguese hospitals.

SIGNIFICANCE AND IMPACT OF THE STUDY

These findings may have implications on the knowledge of healthy health care workers as vehicles of MRSA infections among the community. Presence of several virulence factors may contribute to increased pathogenesis in case of infection.

On the geometric growth in a class of homogeneous multitype Markov chain

In this paper, we investigate the geometric growth of homogeneous multitype Markov chains whose states have nonnegative integer coordinates. Such models are considered in a situation similar to the supercritical case for branching processes. Finally, our general theoretical results are applied to a class of controlled multitype branching process in which the control is random.

Bisexual Galton-Watson branching process with population-size-dependent mating

In this paper, we introduce a bisexual Galton-Watson branching process with mating function dependent on the population size in each generation. Necessary and sufficient conditions for the process to become extinct with probability 1 are investigated for two possible conditions on the sequence of mating functions. Some results for the probability generating functions associated with the process are also given.

A journey across perversions history – from Middle Age to DSM

Introduction

Psychiatry's viewpoint of sexual deviance has waved between the normal and the pathological. “Normal” is not determined by nature but by the values of a specific society.

Aims

To review the main landmarks in paraphilias history and the importance of social and cultural dimensions to it.

Methods

PubMed database was searched using the keywords perversion, sexual deviance, paraphilia, culture and society.

Throughout Middle Age and Renaissance any sexual act that differed from the natural/divine law was considered a vice. Unnatural vices (masturbation, sodomy, bestiality) were the most severely punished, as they could not result in conception. In 1886, Krafft-Ebing stated perversions were functional diseases of the sexual instinct caused by “hereditary taintedness” in the family pedigree and worsened by excessive masturbation. Proper perversions were sadism, masochism, antipathic sexuality (homosexuality, transvestism, transsexuality) and fetishism. Later, Havelock Ellis and Hirschfeld claimed sexual interest in the population followed a statistical norm, opposed the idea that masturbation led to diseases and demanded the decriminalization of homosexuality. Freud believed the “perverse disposition” to be universal in the childhood giving rise to healthy and pathological adult behaviors. In 1950's, Albert Kinsey surprised America when he proved many supposedly deviant sexual practices were quite common. The first Diagnostic and Statistical Manual (1952) was mainly psychoanalytic. Later, by 1973, homosexuality was removed from classifications. Recently, DSM-5 distinguishes between paraphilias and paraphilic disorders.

Conclusion

A progress in the paraphilic instincts’ acceptance has occurred. We hypothesize, in the future, paraphilias will follow homosexuality out of the diseases’ classifications.

Anisakis infection in allis shad, Alosa alosa (Linnaeus, 1758), and twaite shad, Alosa fallax (Lacépède, 1803), from Western Iberian Peninsula Rivers: zoonotic and ecological implications

Spawning individuals of allis shad, Alosa alosa (Linnaeus, 1758), and twaite shad, Alosa fallax (Lacépède, 1803), were sampled from three rivers on the Atlantic coast of the Iberian Peninsula (Ulla, Minho, Mondego) during 2008 to 2013 to assess the presence of the zoonotic marine parasite Anisakis spp. larvae. The results revealed that both shad species were infected by third-larval stage Anisakis simplex s.s. and Anisakis pegreffii. The latter is reported in mixed infections in both shad species of Western Iberian Peninsula for the first time. In A. alosa, the prevalence of Anisakis infection can reach 100%, while in A. fallax, prevalence was up to 83%. Infected individuals of the former species also often contain much higher number of parasites in theirs internal organs and flesh: from 1 to 1138 Anisakis spp. larvae as compared to 1 to 121 larvae, respectively. In general, numbers of A. pegreffii were higher than those of A. simplex s.s. Our results suggest that in the marine environment of the Western Iberian Peninsula, both anadromous shad species act as paratenic hosts for A. simplex s.s. and A. pegreffii, thus widening the distribution of the infective nematode larvae from the marine to the freshwater ecosystem. This finding is of great epidemiological relevance for wildlife managers and consumers, considering the zoonotic and gastroallergic threats posed of these parasites.

[Vocal and behavioral adaptations of program sellers in work situation]

Are program sellers at the Parisian Operas at risk of developing vocal problems? What are the adaptations they use to be heard and understood in this loud environment? Six program sellers were recorded and observed at work. The methodology applied included a questionnaire, acoustic analysis of the records, a videolaryngostroboscopic examination, analysis of objective and subjective measures of vocal function. The results confirmed the existence of voice risk factors and symptoms of vocal fatigue that may justify a preventive intervention. The adaptations that program sellers carry out follow the characteristics of what is called "Lombard Speech". In addition, announces reveal common and individual specificities such as prosodic and acoustic types.

Cellulose morphology and enzymatic reactivity: A modified solute exclusion technique

An expeditious and accurate simplification of Stone and Scallan's solute exclusion technique was developed, thereby avoiding several sources of experimental error coupled with the determination of cellulose pore volume. Using this method, it is shown that cellulolytic enzymes do not enter into the micropores of five studied celluloses. These results suggestes that hydrolysis occurs initially at the external surface of the fibers. This surface area was calculated with the help of adsorption isotherms of bovine serum albumin. The obtained values for the different samples agree with the microscopically observed cellulose morphology. The correlation obtained by several authors relating cellulose porosity and its digestibility is explained as a consequence of the lower crystallinity and easier fragmentation of the more porous celluloses during hydrolysis.

Increased conjunctival expression of protease activated receptor 2 (PAR-2) in seasonal allergic conjunctivitis: a role for abnormal conjunctival epithelial permeability in disease pathogenesis?

AIMS

Aeroallergen exposure to the conjunctival epithelium in seasonal allergic conjunctivitis (SAC) may induce a cellular stress response that disrupts the barrier properties of the conjunctival epithelium, resulting in allergic disease. Whether such changes occur in SAC is unknown. Epithelial permeability is known to be increased when protease activated receptor 2 (PAR-2) is activated. We evaluated the expression of PAR-2 in patients with SAC-in-season (SACS) and compared it with control non-atopic subjects or those with out-of-season allergic conjunctivitis (OSAC).

METHODS

Six SACS, eight normal and four OSAC specimens were examined immunohistochemically for PAR-2 and quantified in a masked fashion for the percentage of epithelia stained for each marker using Image-J software. Conjunctival epithelial heights were measured in all groups to confirm the presence of allergic eye disease.

RESULTS

Mean percentage staining of PAR-2 was significantly greater in SACS that in normal specimens (73.4 ± 15.4% vs 32.8 ± 30.0%, p=0.038) or in OSAC (73.4 ± 15.4% vs 1.4 ± 2.2%, p=0.01). Mean conjunctival epithelial height was significantly raised in SACS (63.8 ± 9.0 μm) versus controls (44.7 ± 11.2 μm) (p=0.003, unpaired t test).

CONCLUSIONS

Conjunctival epithelial PAR-2 is significantly upregulated in SAC. This supports the view that disruption of the barrier properties of the conjunctival epithelium is an important event in SAC pathogenesis.
