Ice Slurry Ingestion Does Not Enhance Self-paced Intermittent Exercise in the Heat

This study aimed to determine if ice slurry ingestion improved self-paced intermittent exercise in the heat. After a familiarisation session, 12 moderately trained males (30.4 ± 3.4 year, 1.8 ± 0.1 cm, 73.5 ± 14.3 kg, inline imageO2max 58.5 ± 8.1 mL/kg/min) completed two separate 31 min self-paced intermittent protocols on a non-motorised treadmill in 30.9 ± 0.9 °C, 41.1 ± 4.0% RH. Thirty minutes prior to exercise, participants consumed either 7.5 g/kg ice slurry (0.1 ± 0.1 °C) (ICE) or 7.5 g/kg water (23.4 ± 0.9 °C) (CONTROL). Despite reductions in Tc (ΔTc: −0.51 ± 0.3 °C, P < 0.05) and thermal sensation prior to exercise, ICE did not enhance self-paced intermittent exercise compared to CONTROL. The average speed during the walk (CONTROL: 5.90 ± 1.0 km, ICE: 5.90 ± 1.0 km), jog (CONTROL: 8.89 ± 1.7 km, ICE: 9.11 ± 1.5 km), run (CONTROL: 12.15 ± 1.7 km, ICE: 12.54 ± 1.5 km) and sprint (CONTROL: 17.32 ± 1.3 km, ICE: 17.18 ± 1.4 km) was similar between conditions (P > 0.05). Mean Tsk, Tb, blood lactate, heart rate and RPE were similar between conditions (P > 0.05). The findings suggest that lowering Tc prior to self-paced intermittent exercise does not translate into an improved performance.

Dependent Adult Abuse A Guide for Mandatory Reporters, July 2009

“Dependent adult” abuse allegations involve people who are aged 18 or over and are incapable of adequate self care due to physical or mental conditions and require assistance from other people. Dependent adults may be elderly or may have diminished physical or mental capacities that prevent them from meeting their own needs adequately. Researchers estimate that only 1 in 14 incidents of elder abuse actually come to the attention of law enforcement or human service agencies. Elder abuse is one of the most under-recognized and under-reported social problems in the United States. It is far less likely to be reported than child abuse because of the lack of public awareness. Nationally, it is estimated that over 55% of elder abuse is due to self-neglect. Such abuse can happen anywhere … in private homes, at health care facilities and in the community at large. Iowa has an increasing proportion of people who are aged 60 or over. The number of persons 80 or over is increasing more rapidly than any other age group. Iowa’s proportion of older adults in the population exceeds that of the United States as a whole.

Intellectual Capital Disclosures: The effect of mandatory Integrated Reporting

Purpose – The purpose of this thesis is to investigate how mandatory obligation to follow the International <IR> Framework while producing the corporate reports influence the intellectual capital disclosures in the reports. Research design – The study uses a disclosure scoreboard to score a selected sample of annual reports depending on whether it disclose intellectual capital information or not. The sample consists of companies listed in South Africa were it is mandatory to follow the integrated reporting framework and companies listen in Sweden where it is not mandatory to produce an integrated report. Empirical results and conclusion – The results of this thesis indicates that the mandatory use of the International <IR> Framework have an impact on the amount of intellectual capital disclosures. Further it concludes that higher level of compliance with the framework further increases the intellectual capital disclosure. Contribution – This study has been an early step towards concluding whether the use of integrated reporting has any effect on the amount of intellectual capital information disclosed in companies’ annual report.

Arterial entrapment syndrome in the cubital fossa: a rare cause of acute stress-related arterial thrombosis in a patient with brachial artery duplication

Arterial entrapment syndrome (AES) at elbow level is very rare and to our knowledge no case of AES by lacertus fibrosus in the cubital fossa in presence of brachial artery duplication has been described to date. We describe a rare case of acute arterial thrombosis of one of two brachial arteries highlighted in the cubital fossa which developed after strenuous right elbow flexor muscle activity and hyper-extensions presumably related to AES by lacertus fibrosus at elbow level. A 43-year-old right-handed woman, experienced paleness, coldness and numbness of the right hand, after 8 consecutive hours of gardening. As she worked, her ipsilateral flexor elbow muscles remained in prolonged and inappropriate tension. Clinical examination evidenced the absence of radial artery pulse in the wrist and mild hypothermia in the second and third finger. During surgical exploration two anastomosed brachial arteries were detected in the cubital fossa under the lacertus fibrosus. The lateral superficial brachial artery was occluded. Intraoperative arteriography evidenced brachial artery duplication at the third superior of the arm and normal vascular pattern at the forearm level. In cases of unexplained atypical intermittent upper extremity claudication or acute ischemic symptoms an AES should always be ruled out, particularly when symptoms are exacerbated by strenuous upper extremity activity or when upper limb muscular hypertrophy is evident. In these cases a thorough dynamic clinical and instrumental examination is mandatory to confirm a diagnosis of AES and to avoid possible future ischemic complications.

Evaluation of ventilation performance in public spaces.

Smoking restrictions in the workplace and increased health consciousness at home have seen a sizable reduction in the number of spaces where smoking is permissible. The aim of this study was to investigate the effects of ventilation in public houses, one of the few remaining public spaces where smoking is still socially acceptable. Little is known about the situation with shared occupancies, where relatively large areas are intended to accommodate both smokers and non-smokers. This study clearly identifies potential problems with a simplistic design approach to ventilation and its effectiveness in the context of shared occupancy spaces. A computational fluid dynamics code has been used to model airflows with the aim of identifying inefficiencies in existing ventilation systems.

Le blocage androgénique intermittent versus continu dans le traitement du cancer de la prostate

L’administration du blocage androgénique de façon intermittente pourrait offrir plusieurs avantages dans le traitement du cancer de la prostate. Toutefois, ce mode d’administration demeure controversé. Nous avons donc effectué une revue systématique et méta-analyse d’essais cliniques randomisés afin de comparer l’efficacité et la tolérabilité du blocage androgénique intermittent versus continu. Une analyse de non-infériorité a été effectuée pour la survie avec un seuil préétabli de 1,15 pour la borne supérieure de l’intervalle de confiance (IC). Au total, 15 études étaient éligibles. Le blocage androgénique intermittent était non inférieur au blocage androgénique continu avec un hazard ratio de 1,02 (IC à 95%: 0,93-1,11). Il y avait peu de différence entre les deux groupes pour la qualité de vie globale. Toutefois, plusieurs études ont rapporté une meilleure fonction physique et sexuelle avec le traitement intermittent. Le blocage androgénique intermittent est une alternative thérapeutique acceptable dans le cancer de la prostate.

Efficacité comparée du lavage pulmonaire thérapeutique par ventilation liquidienne totale et par solution diluée de surfactant exogène dans un modèle ovin de syndrome d’inhalation méconiale

Introduction : Le syndrome d’aspiration méconiale (SAM) est une pathologie respiratoire du nouveau-né qui, dans les cas les plus sévères, peut rester réfractaire aux traitements couramment utilisés et nécessiter in fine le recours à une oxygénation membranaire extracorporelle. Le développement d’un ventilateur liquidien par l’équipe Inolivent a ouvert une nouvelle voie thérapeutique en rendant possible l’utilisation de la ventilation liquidienne totale (VLT) qui utilise un perfluorocarbone liquide afin d’assurer les échanges gazeux tout en effectuant un lavage pulmonaire thérapeutique. En 2011, l’équipe Inolivent a montré la supériorité de la VLT pour retirer le méconium et assurer les échanges gazeux de façon plus efficace que le traitement contrôle, le lavage thérapeutique avec une solution diluée de surfactant exogène (S-LBA). À ce jour, il n’a jamais été montré la possibilité de ramener des agneaux en respiration spontanée au décours d’une VLT pour le traitement d’un SAM sévère. Les objectifs de cette étude sont i) montrer la possibilité de ramener des agneaux nouveau-nés en respiration spontanée sans aide respiratoire après le traitement d’un SAM sévère par VLT, ii) comparer l’efficacité avec le lavage par S-LBA. Méthodes : 12 agneaux nouveau-nés anesthésiés et curarisés ont été instrumentés chirurgicalement. Après l’induction d’un SAM sévère, les agneaux ont subi un lavage pulmonaire thérapeutique soit par VLT (n = 6) ou par S-LBA (n = 6). Les agneaux ont été sevrés de toute ventilation mécanique et suivit en respiration spontanée durant 36 h. Résultats : Il est possible de ramener en respiration spontanée des agneaux nouveau-nés traités par VLT pour le traitement d’un SAM sévère. Le temps nécessaire au sevrage de la ventilation mécanique conventionelle a été plus court chez le groupe S-LBA. Conclusion : Notre étude met en lumière pour la première fois connue à ce jour, la possibilité de ramener en respiration spontanée des agneaux nouveau-nés suivant une VLT dans le traitement d’un SAM sévère. Ces résultats très importants ouvrent la voie à des études sur l’utilisation de la VLT dans le traitement de détresses respiratoires aigües.

Do simple ventilation and gas exchange measurements predict early successful weaning from respiratory support in unselected general intensive care patients?

Background. The value of respiratory variables as weaning predictors in the intensive care unit (ICU) is controversial. We evaluated the ability of tidal volume (Vtexp), respiratory rate ( f ), minute volume (MVexp), rapid shallow breathing index ( f/Vt), inspired–expired oxygen concentration difference [(I–E)O2], and end-tidal carbon dioxide concentration (PE′CO2) at the end of a weaning trial to predict early weaning outcomes. Methods. Seventy-three patients who required .24 h of mechanical ventilation were studied. A controlled pressure support weaning trial was undertaken until 5 cm H2O continuous positive airway pressure or predefined criteria were reached. The ability of data from the last 5 min of the trial to predict whether a predefined endpoint indicating discontinuation of ventilator support within the next 24 h was evaluated. Results. Pre-test probability for achieving the outcome was 44% in the cohort (n¼32). Non-achievers were older, had higher APACHE II and organ failure scores before the trial, and higher baseline arterial H+ concentrations. The Vt, MV, f, and f/Vt had no predictive power using a range of cut-off values or from receiver operating characteristic (ROC) analysis. The [I–E]O2 and PE′CO2 had weak discriminatory power [areaunder the ROC curve: [I–E]O2 0.64 (P¼0.03); PE′CO2 0.63 (P¼0.05)]. Using best cut-off values for [I–E]O2 of 5.6% and PE′CO2 of 5.1 kPa, positive and negative likelihood ratios were 2 and 0.5, respectively, which only changed the pre- to post-test probability by about 20%. Conclusions. In unselected ICU patients, respiratory variables predict early weaning from mechanical ventilation poorly.

Multicomponent cognitive-behavioral therapy for intermittent explosive disorder by videoconferencing: a case study

Cognitive-behavioral Therapy (CBT) for the treatment of Intermittent Explosive Disorder (IED) has proved to be effective, with moderate to large effect sizes both in individual and group interventions. Videoconferencing has been used effectively to treat different mental disorders but its use for IED patients is as yet unknown. The aim of this study is to provide preliminary evidence of the possibility of treating IED by videoconference. We present a case-study experiment of a Spanish male, aged 33 years, living and working in China. After the intervention, the patient's aggressive episodes decreased dramatically, as well as his negative affect. In contrast, he showed an important increment in positive emotions and self-esteem. There were also positive changes in some personality dimensions and facets measured by NEO-PI-R, specifically in neuroticism, extraversion, and agreeableness. The benefits were maintained at 3-, 8- and 18-month follow-ups. These preliminary results reveal that CBT by videoconference oriented to increasing emotion regulation skills was effective when implemented in a case study of a person suffering from IED.

Characterization of patients undergoing noninvasive ventilation admitted in unit intermediate care

Non-invasive ventilation (NIV) is the application of a ventilatory support without resorting to invasive methods. Today it’s considered a credible therapeutic option, with enough scientiic evidence to support its application in various situations and clinical settings related to the treatment of acute respiratory disease, as well as chronic respiratory disease. Objectives: Characterize patients undergoing NIV admitted in Unit Intermediate Care (ICU) in the period from October 1st 2015 to June 30th 2016. Methods: Prospective study conducted in ICU between October 2015 and June 2016. In this study were included all patients hospitalized in this unit (ICU) and in that time period a sample of 57 participants was obtained. As data collection instruments we used a questionnaire for sociodemographic and clinical data and the Braden scale. Results: Participants were mostly male 38 (66.7%), the average age 69.5 ± 11.3 years, ranging between 43 and 92 years. They weighed on average 76.6 kg (52 and 150), with an average body mass index of 28.5 kg/m2 (20 to 58.5). With skin intact 28 (49.1%) with abnormal perfusion 12 (21.1%), with altered sensitivity 11 (19.3%) and a high risk of ulcer on the scale of Braden 37 (65%). The admission diagnosis was respiratory failure 33 (57.3%) and had different backgrounds. We used reused mask 53 (93.0%), the average time of NIV was 7.1 days (1-28), 4.8 days of hospitalization (1-18) and an average of 7.8 IPAP pressure. 11 (19.3%) of the participants developed face ulcer pressure.Conclusions: The NIV is used in patients with advanced age, obesity, respiratory failure and high risk of face ulcer development.

EFFECT OF INTERMITTENT FRYING ON FATTY ACIDS, VITAMIN E, LIPID OXIDATION AND ACRYLAMIDE IN OILS AND PLANTAIN CHIPS COLLECTED FROM SMALL- SCALE PRODUCERS IN CAMEROON

Deep-fat frying is susceptible to induce the formation of undesirable products as lipid oxidation products and acrylamide in fried foods. Plantain chips produced by small-scale producers are sold to consumers without any control. The objective of this study was to evaluate the quality of plantain chips from local producers in relation to production process parameters and oils, and to identify the limiting factors for the production of acrylamide in plantain chips. Samples of frying oils and plantain chips prepared with either palm olein or soybean oil were collected from 10 producers in Yaoundé. Quality parameters determined in this study were: fatty acid composition of the oils, determined by gas chromatography (GC) of free acid methyl ester; trans fatty acids, determined by Fourier transform infra-red spectroscopy; Tocopherols and tocotrienols as markers of nutritional quality were analyzed by High Performance Liquid Chromatography in isocratic mode. Free fatty acids and acylglycerols as markers of lipid hydrolysis were analyzed by GC of trimethylsilyl derivatives of glycerides. Conjugated dienes, Anisidine value and viscosity as markers of lipid oxidation and thermal decomposition of the oils; acrylamide which is formed through Maillard reaction and identified as a toxic compound in various fried products. Asparagine content of the raw fresh plantain powder was also determined. Fatty acid composition of palm oleins was stable within a day of intermittent frying. In soybean oils, about 57% and 62.5% of linoleic and linolenic acids were lost but trans fatty acids were not detected. Soybean oils were partly hydrolysed leading to the formation of free fatty acids, monoacylglycerols and diacylglycerols. In both oils, tocopherols and tocotrienols contents decreased significantly by about 50%. Anisidine value (AV) and polymers contents increased slightly in fried palm oleins while conjugated hydroperoxides, AV and polymers greatly increased in soybean oils. Acrylamide was not detected in the chips. This is explained by the absence of asparagine in the raw plantains, the other acrylamide precursors being present. This study shows that the plantain chips prepared at the small-scale level in Yaounde with palm olein are of good quality regarding oxidation and hydrolysis parameters and the absence of acrylamide. In contrast, oxidation developed with soybean oil whose usage for frying should be questioned. Considering that asparagine is the limiting factor for the formation of acrylamide in plantain chips, its content depending on several factors such as production parameters and maturity stage should be explored.
