Non-invasive electrical stimulation in the form of neuromuscular electrical stimulation (NMES) and functional electrical stimulation (FES) has been documented as an optional assessment and treatment technology for decades. In contrast, translation of the robust clinical evidence supporting the effectiveness of FES’ enhancement of muscle force generation and adding to the recovery of motor control following damage to the brain appears limited. Furthermore, enabling many patients to regain locomotion ability though utilization of FES as a standard care option in rehabilitation medicine remains unmet. This perspective evolved over years of collaborative experience in clinical research, teaching, and patient care having a common goal of advancing patients’ rehabilitation outcomes. The clinical successes are supported by repeated evidence of FES utilization across the life span, from toddlers to elders, from hospitals’ critical care units to the home environment. The utilization include managing multiple deficits associated with the musculo-skeletal, neurological, cardio-pulmonary, or peripheral vascular systems. These successes were achieved in no small part because of the technological advancement leading to today’s wearable wireless FES systems that are being used throughout the continuum of rehabilitation care. However, failures to benefit from FES utilization are likewise numerous, collectively depriving most patients from using the technology to maximize their rehabilitation gains. The most critical failures are both clinical and technological. Whereas numerous barriers to NMES and FES utilization have been published, the focus of this perspective is on barriers not considered to date.

Objectives: Care of a person with schizophrenia involves multiple problems, possibly leading to burnout which is a culturally influenced phenomenon. The aim of this study was to investigate burnout and related factors in caregivers of outpatients with schizophrenia. Methods: Subjects included in the study were 40 primary caregivers of outpatients with schizophrenia (15 males, 25 females) whom were assessed with the Maslach Burnout Inventory (MBI), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). Patients were also administered the Calgary Depression Scale (CDS). Also, sociodemographic information about patients and their caregivers were taken. The significance of differences between two groups was determined by Mann-Whitney U-test. The relationships between the variables were evaluated by Pearson correlation analysis. Results: No significant difference was found in the MBI subscale scores in terms of caregivers gender, marital status, and education, being a family member, having enough information about the illness and taking support during caregiving. Emotional Exhaustion and Personal Accomplishment subscale scores of the caregivers were significantly different in terms of patients’ adaptation to treatment or not (respectively; p=0.010, p=0.030). The MBI-Emotional Exhaustion scores revealed significant positive correlations with the BDI and BAI total scores. Also, the MBI- Depersonalization scores and the BAI scores were positively correlated. Conclusions: Burnout levels in caregivers of patients with schizophrenia were lower when compared with other cultures. Only treatment compliance predicted burnout, while other factors were excluded. Therefore, professionals have to help to patients primarily adapt to their treatment.

Depressive disorders are so frequent and disabling health conditions which have been inarguably accepted to be a public health concern [1]. Many drugs have been developed to treat depression, however the efficacy of the antidepressants are inadequate particularly for mild or moderate depression [2-4]. It is also mentioned that when considering the trials about the treatment effect of the antidepressants, you should be careful about the results because of reflecting a small proportion of the society [4]. Despite the methodological issues related to the controversial results about the antidepressant efficacy, a recent review showed that the antidepressant effects of the drugs persist in a six month period [5,6].

Internal jugular vein catheters (IJC) is recommended as the central venous access of choice in haemodialysis patients. However it is associated with complications of variable severity. Objectives: To study the complications associated with internal jugular vein catheters in haemodialysis patients in southern part of Nigeria. Methodology: The clinical details of patients who had IJC insertion at the kidney house, Hilton clinics Port Harcourt from 1st October 2011 to 30th September 2016 were documented. Complications from the IJC developed by the patients during the study period were also documented. The data obtained was analyzed using SPSS version 22. P value less than 0.05 was considered significant. Results: A total of 129 patients had 150 internal jugular catheter insertions. The mean age was 51.4±15.2 years with male to female ratio of 1.5:1. All the patients had chronic kidney disease; about 80% had tunneled IJC and 96.9% of the catheters were inserted in the right internal jugular vein. Immediate complications were recorded in 10% and late complications in 34.9% of the procedures. The immediate complications were kinking of guide wire (2%), arterial puncture (1.3%) and difficulty in locating the internal jugular vein (1.3%) or tunneling (1.3%). The late complications were infection (12.8%), poor blood flow (9.2%), bleeding (5.5%) and spontaneous removal of the catheter (5.5%). There was no statistical significant difference in both immediate and late complication with age and sex. The ultrasound examination at discharge had a sensitivity of 31% and specificity of 87% to detect future symptomatic lymphoceles. The positive predictive value was only 10%. The second ultrasound test had the best test variables to detect symptomatic lymphoceles with a sensitivity of 93% and a specificity of 87% and a predictive value of 28%. Conclusion: Internal jugular catheter is froth with immediate and late complications in haemodialysis patients.

Introduction: With the availability of different post systems and various studies on the strength of teeth restored with posts, the controversy as to which post systems provide better stress distribution of post and longevity of tooth has not been resolved. The purpose of this study was to compare the stress distribution of three different post materials using finite element analysis. Materials and nethod: Three dimensional finite element models of central incisor, three posts with crown were constructed on computer with software. Posts of three different materials (Ni-Cr post, Glass fiber post, and Zirconia post)with zirconia crown were virtually generated and a force of 100 N was applied at an angle of 450 on the palatal surface of the crown. Von Mises stresses were evaluated on the cervical, middle and apical third of the root. Results: The maximum stresses were seen on the cervical one-third in each post material indicating that this region is more prone to fracture in tooth restored with posts. Among the three materials tested, Ni-Cr post showed maximum stress generation followed by Zirconia post and glass fiber post. The maximum stresses generated by the posts were 11.4 MPa, 10.58 MPa and 4.11 MPa respectively. Conclusion: The less rigid post material like glass fiber post can be used in an endodontically treated anterior teeth.

Background: Hyperuricosuria, persistently low urinary pH, and low urinary volume are the main risk factors of uric acid nephrolithiasis. Epidemiologic studies suggest that high water intake is protective against the occurrence of symptomatic kidney stone events of all types. The objective of this systematic review and meta-analysis were to evaluate the effectiveness of increased water intake to prevent symptomatic uric acid kidney stone events. Methods: Seventeen studies were identified for the meta-analysis. Analysis of Q and I2% statistics revealed that a high heterogeneity in 16 studies, thus, random effects model was used. Protective associations were identified for high water intake individuals (SMD=0.52 L; 95% CI: 0.19, 0.84; p=0.002); a significantly decreased relative super saturation of uric acid versus controls (SMD=-1.15; 95% CI: -2.00, -0.30; p=0.008). Risk factors including urinary uric acid excretion and pH were not significantly related to high water intake (SMD=7.32mg/d, 95% CI: -52.27, 66.91; p=0.81), (SMD=0.14; 95% CI: -0.02, 0.31; p=0.09), respectively. Further subgroup analyses revealed that urinary uric acid excretion was significantly decreased in healthy individuals (SMD=-36.23 mg/d, 95% CI: -65.14, -7.31; p=0.001) compared to stone formers (SMD=27.41 mg/d, 95% CI: -33.18, 88.01; p=0.38); urinary uric acid excretion was significantly decreased in routine water intake groups (SMD=-61.49 mg/d, 95% CI: -120.74, 12.24; p=0.04) compared to mineral water intake groups (SMD=44.50 mg/d, 95% CI: -18.30, 107.29; p=0.16); urinary pH was significantly higher in mineral water groups (SMD=0.13, 95% CI: 0.01, 0.46; p=0.04) compared to regular water groups (SMD=-0.00, 95% CI: -0.13, 0.13; p=0.98). Results: A total of 129 patients had 150 internal jugular catheter insertions. The mean age was 51.4±15.2 years with male to female ratio of 1.5:1. All the patients had chronic kidney disease; about 80% had tunneled IJC and 96.9% of the catheters were inserted in the right internal jugular vein. Immediate complications were recorded in 10% and late complications in 34.9% of the procedures. The immediate complications were kinking of guide wire (2%), arterial puncture (1.3%) and difficulty in locating the internal jugular vein (1.3%) or tunneling (1.3%). The late complications were infection (12.8%), poor blood flow (9.2%), bleeding (5.5%) and spontaneous removal of the catheter (5.5%). There was no statistical significant difference in both immediate and late complication with age and sex. Conclusion: This meta-analysis identified evidence that urinary uric acid excretion, volume, pH and relative supersaturation of uric acid can be altered with high water intake intervention, reducing the risk of uric acid kidney stones.

Introduction: Number of obese people is growing on a daily basis in Brazil, including morbid obese ones, but there is still a lack of studies with this subject. Due to this, the main goal of this study was to identify body profile, physiological variables behavior and oxygen consumption in grade III obese women, submitted to an ergospirometric test in arm ergometer. Method: Take part in this study, thirteen (13) female grade III obese patients between 20 and 40 years. They were submitted to an electric bioimpedance test for body composition measurement and an Ergospirometric test in arm ergometer for oxygen consumption, heart rate, and oxygen saturation, systolic and diastolic arterial pressure, resting and after exercises, analysis. Results: The patients revealed a BMI of 46.5±3.81 kg/m², 51.9±1.59% of body fat percentage. The patients reached 168.2±4.57bpm of heart rate, didn’t make any hypertensive response to the effort reaching an arterial pressure of 171.1±22.15mmHg x 87.5±4.18mmHg. Oxygen saturation was 98±0.71% and oxygen consumption peak was, also in average, 12.3±2.75ml.kg.min-1. Conclusion: It was verified that there was no oxygen saturation drop nor hypertensive response and all of the patients reached the maximum heart rate. 

It is known today that psycho-trauma and PTSD cause different levels of mental and social dysfunction. Human spirituality and capacity to meet further life difficulties become severely damaged. There is wide accepted attitude today that in holistic approach in process of healing PTSD and psycho-trauma is necessary to include other professionals from community resource regarding needs of trauma victims. In Bosnia and Herzegovina after very severe war (1992-1995) as mental health professionals, we are faced with increasing number of different mental health disorders as result of severe trauma experiences. Regarding community based care orientation it is necessary to include and religion professionals. According national and religious background of majority of our population in Tuzla Canton that is Muslim, we meet spiritual needs of our clients as needs for Islamic explanation of life and death meaning. Our clients need to talk about spiritual issues in daily therapy and to practice daily religious rituals. Regarding that in this paper we tried to interface Islamic principles and it’s beneficial toward psycho-trauma and PTSD, as well as Muslim perspectives in attempt to apply spiritual practice in therapeutic tools for better efficacy in spiritual healing of mental dysfunction’s of believers who survived severe trauma, especially war trauma.

In 1955, nutrient malabsorption following upper gut surgery was shown to be related to altered upper gut microbiome. In individuals with abdominal symptoms after Roux-en-Y gastric bypass, we have reported that small intestinal glucose malabsorption is associated with upper gut bacterial overgrowth. We hypothesize that individuals with abdominal symptoms after vertical sleeve gastrectomy have glucose malabsorption associated with upper gut bacterial overgrowth, and to test this hypothesis, bacterial overgrowth and potential glucose malabsorption are examined after sleeve gastrectomy. This is a retrospective study of individuals with medically-complicated obesity who underwent sleeve gastrectomy from 2013 to 2016 with subsequent glucose hydrogen breath testing to evaluate abdominal symptoms. A fasting breath hydrogen or methane of ≥10 PPM or rise of ≥8 PPM ≤45 minutes after oral glucose is bacterial overgrowth, while glucose malabsorption is a second rise of ≥8 PPM at >45 minutes. Seven females (mean age: 48.0 years; mean body mass index at surgery: 45.7 kg/m2) are described. Five subjects (71%) have an early rise in hydrogen or methane, while three (43%) have a second rise in hydrogen or methane >45 minutes after glucose. The mean percent excess weight loss at one year was 40% in three individuals with a second peak and 46% in four subjects without a second peak. After sleeve gastrectomy, subjects have glucose malabsorption associated with the presence of bacterial overgrowth. Completion of a larger prospective study is needed to confirm and expanding upon these findings. Further work should examine the potential effects of bacterial overgrowth on expression of intestinal glucose transporters.

The patient with an oncological disease presents a series of discomforts related to the psychological sphere such as depression, pain, sense of usefulness, anger, but also inconveniences related to food sphere. Neoplastic disease interferes with eating behaviour for several reasons. The communication of the diagnosis can create a state of anorexia as a result of the shock; certain tumours of the gastrointestinal tract-gold (mouth, esophagus, stomach, colon and rectum, but also pancreas and liver) are directly responsible for the possible alteration of food intake; alteration in eating behaviour may be secondary to the main therapeutic treatments. The link between food and cancer is not only evident in case of disease, but also in case of prevention, in fact a growing number of studies indicates more an more clearly the close correlation between a healthy diet and prevention of oncological diseases although at present time it is not still possible to give definitive results. The diagnosis of a person is like a melody in which some notes are repeated but their combination is almost infinite, because each person has different eating needs, as well as different psychological needs, and the starting point for a good professional must necessarily be a ‘customized’ diagnosis. This ‘diagnosis of well-being’, tailor-made for each person, involves professionals in both the food and psychological and behavioural sectors, since the individual needs have to be evaluated globally. Finally, the professionals of human behaviour in food consumption, and the chemical and science processing experts, have the duty not to limit themselves to a single refusal against the use of certain foods, but framing the phenomenon in a wider perspective and, as experts of human health, to propose alternatives.

Maxillofacial defects are very common and can be due to congenital defect, trauma, infections and neoplasms of facial region. These defects can be restored using different materials and retention methods to give a life like appearance. Rehabilitation of facial defect is a very challenging task. Every good prosthesis needs a skillful hand and it all starts with making a good impression of that defect and to proceed with the same. The aim of present paper was to present a simplified approach for the fabrication of custom tray to take facial impression of the patient with maxillofacial defect.

Background: A structured multidisciplinary team is very important during every phase of the amputation process and a good communicative team guarantees a greater tranquility for the patient, thanks to more homogenous information, that is already discussed between the clinicians. Aim: The aim of this study was to define the efficacy and outcome value of an innovative procedure tool (TRIA-MF protocol) in the treatment of lower limb amputees before and after prosthesis use with the purpose to quantify the quality of the procedure and its economic impact on the clinical patients’ recovery. Setting: A rehabilitation institute for the treatment of neurological and orthopaedic gait disorders. Methods: 12 patients (4 women and 8 males) subjected to lower limb amputation and admitted according to the principles of inclusion criteria of the TRIA-MF protocol at the Rehabilitation Department of the Clinical Institute Città di Brescia were recruited in this study. All patients were included in an integrated and task-specific management protocol of the amputee, which allowed to follow the rehabilitation process from amputation to the final restoration, for a period of 6 months for each patient. Patients were evaluated 5 times during the study, collecting their degree of pain (VAS), their independence profile (Barthel Index) and the cirtometry of their amputation stump. Data on the duration of their admission to the rehabilitation unit, the inter-time between the amputation and acquisition of the temporary prosthesis, and between temporary prosthesis acquisition and the final prosthesis acquisition were also reported. Results: Patients of our sample, at the end of their hospitalization, highlight a significant modification of the temporal data at 1 month and 6 months from their hospital discharge. A statistical significant increase of the Barthel Index value was observed in all patients recruited in this study proceeding from time T0 to time T4; in the same way, a statistical significant decrease of the VAS scale was observed in all patients recruited proceeding from time T0 to time T4; the cirtometry of the amputation stump (expressed in cm) showed a statistical significant decrease in all patients recruited proceeding from time T0 to time T4. We haven’t observed a statistical significant correlation between the duration of the rehabilitative hospitalization and our clinical data; no statistical significant correlation was observed between the amputation stump cirtometry time-related modification and our intertime data. Conclusions: The protocol was found to be a clear and relevant tool with the definition of the operational profile for each single professional figure involved; it could also be considered as an optimal tool for coding the management and evaluation of the effectiveness of amputee treatment, with a related high reproducibility, sensitivity and specificity profile. In line with the literature, the TRIA-MF protocol has allowed us not to exceed a period of hospitalization in rehabilitation units of more than 23 days, thus showing that it is an excellent tool for optimizing the management costs of the amputee over time.

Introduction: In endodontically treated teeth, dentinal defects such as microcracks can progress to a vertical root fracture and lead to tooth loss. Objective: The present study aimed to evaluate, by micro-computed tomography analysis, the formation of dentinal microcracks during filling removal in endodontic retreatment of root canals filled with gutta-percha and Total Fill BC bioceramic sealer. Methods: Twenty mesial roots of mandibular molars were instrumented and obturated with gutta-percha and Total Fill BC sealer and then the filling material was removed with rotary Protaper Retreatment files. The specimens were scanned before instrumentation, after filling and after retreatment. The transversal images obtained after filling were compared with the images obtained after removal of the filling material. A descriptive statistical analysis was performed. Results: Among the 24.444 cross-sections analyzed, 5.67% presented some type of dentinal defect, with 0.51% in the initial images, 2.58% in the post-filling images and 2.58% in the post-retreatment images. All the dentinal defects identified in the images obtained after the retreatment were already present in the corresponding images after the filling. New dentinal microcracks were not observed after removal of the filling material. Conclusion: Retreatment of mesial roots of mandibular molars filled with a silicate-based root canal filling material do not influence the formation of dentinal microcracks.

The childhood obesity is increased more than three folds in last two decades in developed world. There is nutritional transition seen in the developing world including India. The westernization in diet of the Indian population along with prosperity brings the brunt of overweight and obesity. This has future implications of liver diseases, heart diseases, hypertension, hyperlipidaemia, insulin resistance; malignancies. Mumbai is the prosperous city and an economical capital of India. Also, the rampant use junk food, common outdoor eating’s, no grounds to play for children make the high likelihood that the prevalence of obesity to be higher than rest of the country. It can profoundly affect children’s physical health, social, and emotional well-being and self-esteem. It is also associated with poor academic performance and a lower quality of life experienced by the child. One of the best strategies to reduce childhood obesity is to improve the eating and exercise habits of the entire family. Treating and preventing childhood obesity helps protect the child’s health and has tremendous impact on child’s Physical and academic performance. And hence we at Aastha Bariatrics took initiative and launched ECHO... for a change (‘E’radicating ‘C’Hild ‘H’ood ‘O’besity), a pan Mumbai campaign against childhood obesity. This campaign was done in 15 high schools across Mumbai, which covered in total of 9000 students.

Objectives: Natural disasters confront individuals, communities and governments with the challenge of rebuilding and addressing psychosocial sequelae. With the increasing number of natural disasters it is timely to evaluate the efficacy of interventions and strategies to address the mental health needs of individuals and the community. Method: An evaluation of literature related to the psychological impact of natural disasters, treatment efficacy and government strategies to confront the social and psychological impact of natural disasters for the period 1983-2016 was undertaken. Results: Epidemiological studies following natural disasters despite the use of differing psychological measures demonstrate significant psychological morbidity - anxiety (7-42%), complicated grief (28-41%), depression (6.5-38%), post-traumatic stress disorder (11-89%) and substance misuse (1.3-24%). Intervention studies post-disaster demonstrate efficacy variability. Conclusions: The increase in the number and impact of meteorological and hydrological events since the 1980s and the psychological, social and economic consequences of these events has resulted in the development and implementation of government policies to confront the immediate and long-term adverse outcomes. The focus is typically on resources and infrastructure redevelopment with less focus on social and mental health interventions with long-term evaluation of interventions uncommon. The consequence of natural disasters emphasizes the importance developing strategies to ensure effective evaluated psychosocial interventions are available across at-risk communities.

Ra-223 dichloride is a first-in-class alpha-emitting radiopharmaceutical recently introduced into clinical practice for treatment of men with Castration-Resistant Prostate Cancer (CRPC) and symptomatic bone metastases. Due to the proven benefit on Overall Survival and the favorable toxicity profile, Ra-223 therapy is gaining widespread use in both US and Europe. In this article, we describe the routinary management of patients undergoing Ra-223 treatment in our Institution. Currently, Ra-223 therapy is indicated for 6 intravenous injections (55 kBq per kg of body weight) administered every 28 days. In comparison to other radiopharmaceuticals, Ra-223 handling and administration do not need any additional training for authorized users. Due to the minimal external dose rate emission, Ra-223 dichloride can be delivered in an outpatient setting. Moreover, no particular precautions other than standard hygiene measures must be taken by patients’ family members or caregivers. Ra-223 therapy is associated to a favorable hematologic toxicity profile, while non-hematologic adverse events are generally mild and easy to manage. Given the favorable toxicity profile of this treatment, clinical trials are currently ongoing to evaluate efficacy and safety of Ra-223 treatment in combination or sequence with recently approved drugs such as abiraterone acetate, enzalutamide and sipuleucel-T. In addition, the recent interest in Ra-223 bone lesion dosimetry could open the way to a dosimetric-based therapeutic approach with Ra-223. In this new scenario, results of these promising clinical trials may help clarifying the optimal sequencing of new therapeutic possibilities for metastatic CRPC and the appropriate eligibility criteria for Ra-223 treatment in oncologic patients.

The well recognized white adipose tissue is an endocrinal organ secreting various hormones and this article simply indicates to the physiologic concepts brown fat tissues (BAT) which are extremely active endocrine organs and play various metabolic active roles in intermediate metabolism. The physiologic function of Brown adipose tissues contributes to energy-producing parts of the cell. Its amount is rare up to approximately one hundred and thirty gram and implies important characteristics for mammals. An increase in energy expenditure could be an aim by activation of BAT, seems futurity to reduce body weight that needs a vast majority of fundamental research to facilitate its occurrence [1]. Brown fat tissue generates heat and has valuable importance for human metabolism [2,3]. Brown fat tissue is decreased in overweight and obese people and possibly activating brown fat tissue might help for reducing weight and weight-related metabolic disorders like insulin resistance.

Depression: According Pubmed Health: Depression is a state of low mood and aversion to activity that can affect a person’s thoughts, behavior, feelings and sense of well-being (moderate or severe). Can we consider some depression status due to high amount of some stressant stimulus? Or continuous stress in a limited (or long) period? How can react mindset and brain in management an high amount of negative stressing thinking? Observing some relevant literature also mindset kinetics must be considered to better classify this kind of disorder under a specific endogenous –exogenous biochemical-toxicological aspect. Concept like Kinetics, reaction velocity limits, saturation of the systems, residual buffer properties are currently used in biochemistry and related discipline. This concepts can be applied also in some depression condition to better explain some phenomena?

Oxygen therapy is the main supportive treatment in hypoxemic respiratory failure and has traditionally been delivered using low and high flow devices. However, the maximal flow rates that these devices can deliver are limited because of the insufficient heat and humidity provided to the gas administered. Low flow devices such as the nasal cannula, conventional face mask and reservoir bag deliver a flow rate of up to 15 L/min by administering more variable oxygen fractions (FiO2), depending on the patient’s respiratory pattern, peak inspiratory flow and characteristics of the devices. Conventional high flow devices, such as venturi type masks, utilize a constant flow of oxygen through precisely sized ports, entraining the ambient air, using the Bernoulli principle, providing a more constant inspired oxygen fraction. However, they are less tolerated than nasal cannulas because they are less comfortable and the insufficient humidification and heating of the gas delivered [1]. In the last two decades, new devices have been developed to administer high humidified and heated flow through a nasal cannula (HFNC) that also allows the delivery of oxygen with a known FiO2 up to 100%. In the literature, this technique has also been called mini CPAP (continuous positive airway pressure), transnasal insufflation, high nasal flow ventilation, high flow oxygen therapy, and high flow nasal cannula oxygen therapy [2]. It is considered that high flow nasal cannula has certain benefits compared to those of oxygen therapy previously detailed. HFNC manages a flow of more than 30 L/min, which is able to surpass the peak inspiratory flow of the patient, being able to reach values ​​between 60-80 L/min depending on the flow used. The gas source, which may be delivered by an air/oxygen blender, fans, or a flow generating turbine, is connected by an active humidifier to a nasal cannula and the FiO2 can be adjusted independently of the flow. From a clinical point of view, there is some confusion between venturi and high flow nasal cannula devices. In the literature, both have been considered as high flow oxygen therapy devices. In our opinion this is not appropriate because the high nasal cannula flow is much more than a simple system for administering oxygen therapy [3]. Venturi-type masks provide the patient with a gas mixture with a controlled FiO2, but do not exert additional benefits on the ventilator mechanics of the patient. Nevertheless, HFNC allows the delivery of a high flow, which can also add oxygen therapy, providing a series of physiological effects that imply an active treatment to respiratory failure. Effects related to HFNC include the following: 1. Delivery of higher and more stable FiO2 values, ​​because the flow delivered is greater than the patient’s inspiratory demand. 2. The anatomical dead space decreases by washing the nasopharynx, consequently increases alveolar ventilation. This improves the thoracoabdominal synchrony. 3. Respiratory work decreases because it acts as a mechanical stent in the airway and markedly attenuates inspiratory resistance. 4. The gas administered is warmed and humidified, improving mucociliar clearance, reducing the risk of atelectasis, improving ventilation perfusion and oxygenation ratio. 5. There is a CPAP-like effect. The dynamic positive espiratory airway pressure generated by HFNC reaches a value between 6-8cmH2o depending on the flow and the size of the cannula. This positive pressure distends the lungs and ensures their recruitment. 6. Pulmonary end-expiratory volume is higher with HFCN than with conventional high-flow oxygen therapy. 7. In addition, the technique is considered easy and simple for the medical staff and nurses, and can be used in different areas (emergency, hospitalization, critical care unit, weaning centers) and even at home [4]. Currently available evidence has demonstrated that HFNC therapy is an alternative for the treatment of acute hypoxemic respiratory failure, hypercapnic respiratory failure, acute heart failure, as rescue therapy preventive therapy in post-extubation respiratory failure and in specific conditions such as bronchoscopy [5]. We believe that high-flow nasal cannula treatment should not be confused with high flow oxygen therapy of venturi masks. According to detailed mechanisms of action, HFNC is not limited to being only an oxygen therapy system but also behaves as a true treatment that can be used in different clinical scenarios, generating physiological benefits that result in the reduction of respiratory work. In addition, in venturi type masks, the air is not humidified and complications such as dryness and nasal pain are common, generating a poor tolerance to oxygen therapy. The benefits of proper humidification and heating of the gas delivered with HFNC therapy allow better comfort and tolerance of the patient with easy adherence to the treatment. All this contributes to making HFNC be considered a technique of choice in patients with hypoxemic respiratory failure. The growth in its use associated with easy acceptance for patients and the expansion in its application show us that HFNC is a promising therapy.

The effect of acute administration of ethanol extract of F. thoningii on anxiety and fear in Swiss white mice was studied. 30 adult Swiss white mice of both sexes were randomly divided in to three groups of 10 mice each. Group1 served as the control and was administered normal saline only. Group 2 (low dose group) was administered 10mg/kg ethanol extract of the F. thoningii, while group 3 (high dose group) was given 20mg/kg of the same extract. All animals were allowed food and water ad libitum. Neurobehavioral parameter was assessed using the light/dark transition box. The analysis of variance (ANOVA) was used to test for variability within and among groups. Results were expressed as Mean ±SEM (standard error of the mean) and probability level p<0.05 was accepted as significant. The result showed that the frequency of transition in the light/dark transition box was significantly increased in the test groups (p<0.05; p<0.01).Similarly, the Light Box Duration was also significantly increased (p<0.01) in the low and high dose groups respectively. However, the Dark box duration was significantly decreased (p<0.05; p<0.01) in the low and high dose groups compared to control. This index showed a decreased level of anxiety and fear in the test groups. This was followed by a corresponding trend of decreased frequency of stretch attend posture and duration of freezing in the light/dark transition box (p<0.01; p<0.001) compared to the control. Summarily, acute administration of ethanol extract of F. thonningii causes calmness and sedation in moderate and high doses. It is therefore likely that it reduces aggression. If the result from this finding is extrapolated to humans, F. thoningii could be used to reduce anxiety disorders.
