Predictors to Achieve Normal Nutrition Status: Longitudinal Study Among HIV Children on Antiretroviral Treatment in Bali

Background and purpose: Malnutrition is common in children with HIV/AIDS. Antiretroviral therapy (ART) improves the nutritional status; however, information about predictors affecting the changes of nutritional status is limited and inconsistent.Methods: The retrospective survival study analyzed secondary data of 84 undernourished children receiving ART in Sanglah Central Hospital in 2010 to 2015. Demographic, clinical and socio-economic characteristics at ART initiation were linked to the achievement of normal nutritional status (z-score ? -2 SD). Kaplan Meier analysis was used to obtain the incidence rate and median time and cox proportional hazards models to identify its predictors.Results: Of the 73.81% of children achieved a normal nutrition status with the incidence of children achieving normal nutritional was 19 per 100 child months, and a median time of 4 months 10 days. Children with birth weight ?2500 gr (AHR=5.41; 95%CI: 1.76-16.61), without candidiasis (AHR=3.72; 95%CI: 1.27-10.93), Clinical WHO Stage III (AHR=1.6; (95%CI: 1.08-4.24), Clinical WHO Stage II (AHR=4.49; 95%CI: 1.95-10.79) and early ART intiation (AHR=0.91; 95%CI: 0.83-0.98) were predictors to achieve normal nutritional status.Conclusion: Clinical characteristics of children are predictors of achieving a normal nutritional status

Predictors of Loss to Follow Up and Mortality Among Children ?12 Years Receiving Anti Retroviral Therapy During the First Year at a Referral Hospital in Bali

Background and purpose: Many HIV-infected children in Bali have started antiretroviral therapy (ART), but loss to follow up (LTFU) is a continuing concern, and the issue of childhood adherence is more complex compared to adults.Methods: This was a retrospective study among cohort of 138 HIV+ children on ART in Sanglah General Hospital, Denpasar, Bali from January 2010 to December 2015. Kaplan-Meier analysis was used to describe incidence and median time to LTFU/mortality and Cox Proportional Hazard Model was used to identify predictors. Variables which were analysed were socio-demographic characteristics, birth history, care giver and clinical condition of the children.Results: Mean age when starting ARV therapy was 3.21 years. About 25% experienced LTFU/death by 9.1 month resulting in an incidence rate of 3.28 per 100 child month. The higher the WHO stage, the higher the risk for LTFU/mortality along with low body weight (AHR=0.90; 95%CI: 0.82-0.99).Conclusion: Clinical characteristics were found as predictors for LTFU/mortality among children on ART

A Preliminary Study

Bioelectrical Impedance Spectroscopy (BIS) allows assessing the composition of body districts noninvasively and quickly, potentially providing important physiological/clinical information. However, neither portable commercial instruments nor more advanced wearable prototypes simultaneously satisfy the demanding needs of unobtrusively tracking body fluid shifts in different segments simultaneously, over a broad frequency range, for long periods and with high measurements rate. These needs are often required to evaluate exercise tests in sports or rehabilitation medicine, or to assess gravitational stresses in aerospace medicine. Therefore, the aim of this work is to present a new wearable prototype for monitoring multi-segment and multi- frequency BIS unobtrusively over long periods. Our prototype guarantees low weight, small size and low power consumption. An analog board with current- injecting and voltage-sensing electrodes across three body segments interfaces a digital board that generates square-wave current stimuli and computes impedance at 10 frequencies from 1 to 796 kHz. To evaluate the information derivable from our device, we monitored the BIS of three body segments in a volunteer before, during and after physical exercise and postural shift. We show that it can describe the dynamics of exercise-induced changes and the effect of a sit-to-stand maneuver in active and inactive muscular districts separately and simultaneously

Effects of Fatigue on the Integrity of a Friction Stir Welded Lap Joint Containing Residual Stresses

This research uses a non-destructive method of neutron diffraction to measure the tri-axial residual stresses in a friction stir welded aerospace fuselage component: a stringer-to-skin lap joint. Two different specimens were examined. Fatigue testing was performed on both specimens to determine their fatigue lives. Effects of the different components of residual stresses were examines and related to fatigue performance. A combination of fractography, hardness testing, and residual stress measurement was used to predict areas of high probability of structural failure in the friction stir welded lap joints

The Association of Fatigue With Decreasing Regularity of Locomotion During an Incremental Test in Trained and Untrained Healthy Adults

Fatigue is a key factor that affects human motion and modulates physiology, biochemistry, and performance. Prolonged cyclic human movements (locomotion primarily) are characterized by a regular pattern, and this extended activity can induce fatigue. However, the relationship between fatigue and regularity has not yet been extensively studied. Wearable sensor methodologies can be used to monitor regularity during standardized treadmill tests (e.g., the widely used Bruce test) and to verify the effects of fatigue on locomotion regularity. Our study on 50 healthy adults [27 males and 23 females; <40 years; five dropouts; and 22 trained (T) and 23 untrained (U) subjects] showed how locomotion regularity follows a parabolic profile during the incremental test, without exception. At the beginning of the trial, increased walking speed in the absence of fatigue is associated with increased regularity (regularity index, RI, a. u., null/unity value for aperiodic/periodic patterns) up until a peak value (RI = 0.909 after 13.8 min for T and RI = 0.915 after 13.4 min for U subjects; median values, n. s.) and which is then generally followed (after 2.8 and 2.5 min, respectively, for T/U, n. s.) by the walk-to-run transition (at 12.1 min for both T and U, n. s.). Regularity then decreases with increased speed/slope/fatigue. The effect of being trained was associated with significantly higher initial regularity [0.845 (T) vs 0.810 (U), p < 0.05 corrected], longer test endurance [23.0 min (T) vs 18.6 min (U)], and prolonged decay of locomotor regularity [8.6 min (T) vs 6.5 min (U)]. In conclusion, the monitoring of locomotion regularity can be applied to the Bruce test, resulting in a consistent time profile. There is evidence of a progressive decrease in regularity following the walk-to-run transition, and these features unveil significant differences among healthy trained and untrained adult subjects

Tracheotomy care simulation training program for inpatient providers

Objectives: Tracheotomy complications can be life-threatening. Many of these complications may be avoided with proper education of health care providers. Unfortunately, access to high-quality tracheotomy care curricula is limited. We developed a program to address this gap in tracheotomy care education for inpatient providers. This study aimed to assess the efficacy of this training program in improving trainee knowledge and comfort with tracheotomy care. Methods: The curriculum includes asynchronous online modules coupled with a self-directed hands-on simulation activity using a low-cost tracheotomy care task trainer. The program was offered to inpatient providers including medical students, residents, medical assistants, nurses, and respiratory therapists. Efficacy of the training was assessed using pre-training and post-training surveys of learner comfort, knowledge, and qualitative feedback. Results: Data was collected on 41 participants. After completing the program, participants exhibited significantly improved comfort in performing tracheotomy care activities and 15% improvement in knowledge scores, with large effect sizes respectively and greater gains among those with little prior tracheotomy care experience. Conclusion: This study has demonstrated that completion of this integrated online and hands-on tracheotomy simulation curriculum training increases comfort and knowledge, especially for less-experienced learners. This training addresses an important gap in tracheotomy care education among health care professionals with low levels of tracheotomy care experience and ultimately aims to improve patient safety and quality of care. This curriculum is easily transferrable as it requires only access to the online modules and low-cost simulation materials and could be used in other hospitals, long-term care facilities, outpatient clinics, and home settings
