Introduction. Sleep-related breathing disorders, including sleep apnea and hypoxemia during sleep, are common in pulmonary arterial hypertension (PAH), but the underlying mechanisms remain unknown. Overnight fluid shift from the legs to the upper airway and to the lungs promotes obstructive and central sleep apnea, respectively, in fluid retaining states. The main objective was to evaluate if overnight rostral fluid shift from the legs to the upper part of the body is associated with sleep-related breathing disorders in PAH. Methods. In a prospective study, a group of stable patients with idiopathic, heritable, related to drugs, toxins, or treated congenital heart disease PAH underwent a polysomnography and overnight fluid shift measurement by bioelectrical impedance in the month preceding or following a one-day hospitalization according to regular PAH follow-up schedule with a right heart catheterization. Results. Among 15 patients with PAH (women: 87%; median [25th;75th percentiles] age: 40 [32;61] years; mean pulmonary arterial pressure 56 [46;68] mmHg; pulmonary vascular resistance 8.8 [6.4;10.1] Wood units), 2 patients had sleep apnea and 8 (53%) had hypoxemia during sleep without apnea. The overnight rostral fluid shift was 168 [118;263] mL per leg. Patients with hypoxemia during sleep had a greater fluid shift (221 [141; 361] mL) than those without hypoxemia (118 [44; 178] mL, p = 0.045). Conclusion. This pilot study suggests that hypoxemia during sleep is associated with overnight rostral fluid shift in PAH.

Shwetra (Vitiligo) is a skin disease which takes longer time to cure. It affects the external beauty of the body causing social stigma, shyness, loss of confidence, fear of comments marital problems, etc. The disease needs repeated shodhana and regular internal and external shaman chikitsa for longer duration. Objectives: To study the efficacy of Vishakalpa (Shwetra lepa) alone in the management of Shwetra and to provide a potent drug for sure and quick relief from Shwetra (vitiligo), this pilot study was carried out. Material and methods: Shwetra lepa was prepared and used as local application in 15 patients having newly diagnosed patches of vitiligo. The changes in shape, size and number of patches and VETI score was assessed before and after treatment. The data was analyzed with the help of parametric and non parametric tests. Results: Though there was no significant change in VETI score, minimal reduction in shape and size of patches, daha and kandu was observed with Shwetra lepa vati. Conclusion: One month study duration for local application of Shwetra lepa vati and sample size was found to be insufficient to prove the efficacy of Shwetra lepa. Hence it is recommended that Shwetra lepa should be used alone for longer period up to 6 to 9 months or it can be used along with repeated shodhana and continuous shamana chikitsa for 2 to 6 months for effective results.

Zusammenfassung Die Optimierung der motorischen Leistung und die Einbindung und Vernetzung bisher nicht verwendeter motorischer Einheiten sowie die vermehrte Ausschüttung neurotropher Faktoren sind zentrale Mechanismen der Vibrationswirkung, die therapeutisch auf einzelne Körperteile oder den gesamten Körper angewendet werden können. Eine Möglichkeit, die Frühmobilisation bei kritisch kranken Patienten effektiver zu gestalten und immobilitätsbedingten Veränderungen vorzubeugen, könnte die Verwendung des Vibramoov™-Systems sein. Gezielt programmierte Vibrationssequenzen stimulieren hier das Nervensystem mit sensorischen Informationen, die die Empfindung einer Bewegung nachahmen (z. B. des Gehens) und somit Regenerations- und Reor-ganisationsprozesse im zentralen Nervensystem unterstützen können. Von Bedeutung ist dieser Therapieansatz vor allem bei Patienten, bei denen aufgrund ihres Zustandes konventionelle Maßnahmen nicht oder nur eingeschränkt durchgeführt werden können. Da bisher keine Erfah-rungen zur Anwendung bei intensivpflichtigen Patienten verfügbar sind, wurde eine Pilotstudie durchgeführt mit der Fragestellung, ob diese Therapieform sicher ist und im normalen Betrieb auf der Intensivstation verwendet werden kann. Die Ergebnisse der Pilotstudie mit fünf Patienten zei-gen, dass die Anwendung von Vibramoov™ zu keiner wesentlichen Veränderung kardiopulmo-naler Parameter im Sinne einer Non-Toleranz führte und im klinischen Setting gut umsetzbar war. Schlüsselwörter: Frührehabilitation, Imagination von Bewegung, Intensivstation, Vibramoov™ Imagination of movement through vibrational stimuli – a new approach to early mobilization in intensive care units? A pilot study Abstract The optimization of motor performance and the integration and networking of previously unused motor units, as well as the increased release of neurotrophic factors, are central mechanisms related to the vibration effect that can be applied therapeutically to individual parts of the body or to the entire body. One way to make early mobilization more effective in critically ill patients and to prevent changes due to immobility could be rehabilitation with functional proprioceptive stimulation, also known as “illusory movement”. Specifically programmed vibration sequences stimulate the nervous system with sensory information that mimics the sensation of movement (e. g., walking) and can thus support regeneration and reorganization processes in the central nervous system. This therapeutic approach is particularly important for patients who, due to their condition, cannot – or only to a limited extent – carry out conventional measures. Since no experience has so far been available for use in intensive care patients, we carried out a pilot study to answer the question of whether this form of therapy can be used safely and in normal operations in the intensive care unit. The results of the pilot study with 5 patients showed that the use of Vibramoov™ did not lead to any significant change in cardiopulmonary parameters in terms of non-tolerance and was easy to implement in a clinical setting.

This chapter aims to (1) examine the awareness and experience of undergraduates in Melbourne, Australia of current and potential online risks, (2) explore how undergraduates deal with online incidents, and (3) make policy recommendations on how to enhance e-consumer protection. A total of 802 valid responses were received from the surveys conducted in Melbourne, Australia in 2007-2008. Findings demonstrate that most of the respondents were not aware of online incidents which could lead to credit card fraud. A number of them have encountered online incidents. Also, several respondents would less likely seek help from government and/or non-government organisations when encountering online incidents. Overall, credit card use and risks in the e-market is an under-research area in Australia, and this is a pilot study in this field. Findings from this chapter would contribute to the body of knowledge of credit card use and debt due to online shopping, and e-consumer protection.

Piglets experience welfare issues during the nursery phase. This pilot study aimed to test a protocol for identifying the main welfare issues in suckling piglets and to investigate relationships among animal-based indicators and management conditions. Litters (n = 134), composed of undocked and tail-docked piglets, were assessed at two farms. After birth, observations were made at the age of 7 days and 20 days. At each observation, housing conditions (HCs) were measured, and 13 animal-based indicators, modified from Welfare Quality, Classyfarm, Assurewel and others introduced ex novo, were recorded. A generalized linear mixed model was used, considering animal-based indicators as dependent variables and farm, piglets’ age, tail docking and HCs as independent variables. The main welfare issues were lesions of the limb (32.6%) and the front area of the body (22.8%), a poor body condition score (BCS) (16.1%), ear lesions (15.5%), and tail lesions (9.7%). Negative social behaviour (e.g., fighting and biting) represented 7.0% of the active behaviour, with tail biting observed in 8.7% of the piglets. While lesions on the front areas of the body were mostly associated with the farm, tail lesions, low BCS, tear staining, and diarrhoea were associated with light and nest temperature (p < 0.05). In particular, tail biting increased with scarce light (p = 0.007). Tail docking did not influence any animal-based indicator except for tear staining which was higher in the tail-docked as compared to the undocked piglets (p = 0.05), increasing awareness on this practice as a source of negative emotion in piglets. The protocol tested may be a promising tool for assessing on-farm piglets’ welfare.

ABSTRACT The identification of several simian immunodeficiency virus mac251 (SIVmac251) cytotoxic T-lymphocyte epitopes recognized by CD8+ T cells of infected rhesus macaques carrying the Mamu-A*01 molecule and the use of peptide-major histocompatibility complex tetrameric complexes enable the study of the frequency, breadth, functionality, and distribution of virus-specific CD8+ T cells in the body. To begin to address these issues, we have performed a pilot study to measure the virus-specific CD8+ and CD4+ T-cell response in the blood, lymph nodes, spleen, and gastrointestinal lymphoid tissues of eight Mamu-A*01-positive macaques, six of those infected with SIVmac251 and two infected with the pathogenic simian-human immunodeficiency virus KU2. We focused on the analysis of the response to peptide p11C, C-M (Gag 181), since it was predominant in most tissues of all macaques. Five macaques restricted viral replication effectively, whereas the remaining three failed to control viremia and experienced a progressive loss of CD4+ T cells. The frequency of the Gag 181 (p11C, C→M) immunodominant response varied among different tissues of the same animal and in the same tissues from different animals. We found that the functionality of this virus-specific CD8+ T-cell population could not be assumed based on the ability to specifically bind to the Gag 181 tetramer, particularly in the mucosal tissues of some of the macaques infected by SIVmac251 that were progressing to disease. Overall, the functionality of CD8+ tetramer-binding T cells in tissues assessed by either measurement of cytolytic activity or the ability of these cells to produce gamma interferon or tumor necrosis factor alpha was low and was even lower in the mucosal tissue than in blood or spleen of some SIVmac251-infected animals that failed to control viremia. The data obtained in this pilot study lead to the hypothesis that disease progression may be associated with loss of virus-specific CD8+ T-cell function.

Whole-body Vibration (WBV) is a well- known occupational health hazard in mining industry. Dumper operators are subjected to WBV generated from road-tyre interaction and transmitted through the base of the seat. Dynamic characteristics of vehicle seat are vital contributing factor in determining the quality of a seat in use. The objective of this pilot study was to evaluate the transmissibility factor of pneumatic dumper seats used in an Indian mine. Total fifteen (15) dumpers of two different makes with pneumatic seats were selected for the study purpose. The tri-axial seat-pad accelerometers (SVANTEK make SV 38A) collected data in all three orthogonal axes of translational or rectilinear vibration. The mono-axial or single axis accelerometer (SVANTEK make SV 80 with mounting magnet SA 32) was simultaneously positioned rigidly on the floor to record signals in vertical direction. The data so obtained were then calculated using a vibration risk calculator in MS-EXCEL to quickly predict the health impacts using the measured vibration magnitude along with period of exposure per day. The results obtained clearly indicated that the drivers of all the fifteen (15) dumpers are at moderate risk of adverse health effects. It was clear from the SEAT factor calculated using rms and VDV values that the present seats installed in all the dumpers are not efficient and failed to attenuate the vibrations from the floor to seat and ultimately to the body of the dumper operator. It was observed that further in-depth evaluation of engineering and designing part of the seats used in these types of dumpers is desirable. The future scope of such evaluations must take into consideration the actual working condition to be able to realistically attenuate the vibrations so as to provide comfort and relief to the dump operators in mines.

AbstractExercise training creates a number of physical challenges to the body, the overcoming of which drives exercise adaptation. The balance between sufficient stress and recovery is a crucial, but often under-explored, area within exercise training. Genetic variation can also predispose some individuals to a greater need for recovery after exercise. In this pilot study, 18 male soccer players underwent a repeated sprint training session. Countermovement jump (CMJ) heights were recorded immediately pre-and post-training, and at 24-and 48-hours post-training. The reduction in CMJ height was greatest at all post-training time points in subjects with a larger number of gene variants associated with a reduced exercise recovery. This suggests that knowledge of genetic information can be important in individualizing recovery timings and modalities in athletes following training.
