Impact of Different Variables on Recovery Time in Patients Receiving Hemodialysis

Abstract

Introduction. Patients on hemodialysis (HD) are proven to have impaired Health Related Quality of Life (HRQoL) compared to the general population. Recovery from the hemodialysis session is a permanent problem among majority of patients receiving HD treatment. A partial explanation may be the osmotic imbalance between different compartments of the body due to the fluid and electrolyte movement across the cell membrane which is a part of the HD process itself. The aim of our study was to see whether the length of recovery time (RT) is associated with different clinically relevant variables and dialysis treatment features in our HD population.

Methods. We performed a cross-sectional study on patients receiving trice weekly HD in a single hemodialysis center. The recovery time was defined by posing a single question "How long does it take you to recover after a hemodialysis session?" and was calculated in hours (up to 2, 2-6, 6-12, and 12-24 hours) / minutes. Various demographic and clinical characteristics were analyzed for association with the RT.

Results. The mean RT was 364.62±339.24 minutes. From all of the analyzed variables a significant statistical correlation was obtained with the level of albumin, urea, interdialytic weight gain (IDWG), protein catabolic rate (PCR), body mass index (BMI) and the level of hemoglobin (p<0.05 for all parameters). The longest mean RT had patients with hypertension and glomerulonephritis as a primary cause of ESRD and the shortest, patients with an adult dominant polycystic kidney disease. With the multiple regression analysis a significant correlation was obtained only for the level of hemoglobin (Hb) with a coefficient for partial regression analysis - 0.2635. The t-test showed that the influence of the level of hemoglobin on recovery time in patients was statistically significant (p = 0.039).

Conclusions. RT in our study was associated with IDWG, albumin, urea, BMI, and PCR, while the level of hemoglobin was also shown to have a significant impact on the RT and on patients’ overall health status. Hence, we could conclude that maintaining Hb levels in dialysis patients within reference values among the other benefits, may improve the recovery time and HRQoL of our patients.

The Properties of Water and their Applications for Training

Abstract

The biological effects of immersion in water, which are related to the fundamental principles of hydrodynamics, may be beneficial in certain training contexts. The effects and physical properties of water, such as density, hydrostatic pressure and buoyancy are highly useful resources for training, when used as a counterbalance to gravity, resistance, a compressor and a thermal conductor. Not only does the aquatic medium enable a wider range of activities to be used in a context of low joint impact, but it also constitutes a useful tool in relation to sports rehabilitation, since it allows the athlete to return to training earlier or to continue with high-intensity exercise while ensuring both low joint impact and greater comfort for the individual concerned. Moreover, this medium enables the stimulation of metabolic and neuromuscular systems, followed by their corresponding physiological adaptations allowing both to maintain and improve athletic performance. Hydrotherapy can also play a beneficial role in an athlete’s recovery, helping to prevent as well as treat muscle damage and soreness following exercise.

Insight and recovery and the stigma of mental illness - analysis of the phenomenon of insight in schizophrenia and its correlations with the processes of stigma and self-stigma

Abstract

Does better insight associated with the process of recovery mean a stronger sense of mental illness stigma? This article presents the relationship between a multidimensional construct, which is the insight and the phenomena of stigma and self-stigma of patients diagnosed with schizophrenia. It is well known that the term insight contains: a sense of illness, the patient's attitude to its symptoms, explanation of the causes of the illness, attitude to the rationale of treatment and awareness of the risk of relapse. On the other hand, self-stigma occurs when the patient internalizes and refers to himself/herselfnegative and stigmatizing social attitudes, conditioned by the presence of conventionalbeliefs, strengthened by the media, and this weakens the process of recovery.

How much does good insight strengthen the patient on the way to fuller social functioning, and how much does it imprint stigma of mental illness and weaken its positionin society? The authors of the paper are discussing the subject of insight and stigma from the patient's perspective, over the patient’s attitude towards the diagnosis of schizophrenia, the process of recovery and the aspect of hope - important in recovery. These study of construct insight shows that the relationship insight-recovery-stigma is a multi-dimensional plane, dependent on various factors, that needs constant deepening and complementing with further research.

Sleep Patterns and Alertness in an Elite Super Rugby Team During a Game Week

Abstract

Sleep is a vital component of preparation, performance and recovery for a Super Rugby game. The purpose of this study was to quantify sleep behaviours and alertness of professional rugby union players during training and a game. Thirty-six rugby union players from a Super Rugby team wore a wrist-activity device (Readiband™) to measure sleep for 3 days before, 3 days after and on the night of an evening game. Players were separated into those selected to play the game (n = 23) and those who were not (n = 13). Alertness was assessed for all training and game times using bio-mathematical modelling. Alertness measures ≤90% were considered to reflect impaired reaction time. Those selected to play in the game progressively increased sleep duration over the nights prior to the game (by 92 min p ≤ 0.05) by delaying wake time. Players went to bed later after the game (02:20 ± 114 min vs 22:57 ± 60 min; p ≤ 0.001) which resulted in decreased sleep duration on game night compared to pre-game nights (296 ± 179 min vs 459 ± 78 min; p ≤ 0.05). Four players did not achieve any sleep on game night. Sleep duration appeared to be truncated by early morning training sessions (before 08:00) on the second and third mornings after the game. Alertness was >90% for all training and game times for all players. In conclusion, in the days leading into a Super Rugby game, players delay morning time at wake and consequently increase sleep duration with post-game sleep reduced in some.

The use of the fluidized bed boiler for the disposal of the multi-material packaging waste

The use of the fluidized bed boiler for the disposal of the multi-material packaging waste

The paper presents the results of the disposal of packaging waste from two companies: Tetra Pak and Combibloc, carried out in a fluidized bed boiler of rated thermal power 0.5 MW. The material introduced into the fluidized bed boiler underwent thermal and mechanical degradation in a sand bed of the temperature between 750 and 850°C. The process proceeds auto-thermally, without the need of additional fuel. The appropriately chosen fluidization parameters caused the separation of the solid products of combustion from the deposit material. Presence of aluminum, part of it in an un-oxidized form, was confirmed in separated dust. The gaseous products of combustion contained the traces of oxides of nitrogen and sulfur, mainly originating from the remnants of food products contained in the packaging. However, the concentration of these oxides met the requirements of emission standards.

Heart Rate and Oxygen Uptake Recovery and the Level of Aerobic Capacity in Mountain Bikers

Abstract

Introduction. Since mountain biking involves exercise of varying intensity, competitive performance may be affected by the rate of recovery. The aim of the current study was to determine whether maximal oxygen uptake is associated with the rate of heart rate and oxygen uptake recovery in mountain bike athletes.

Material and methods. The study examined 29 mountain bikers, including members of the Polish National Team. These athletes specialised in cross-country Olympic (XCO) racing. After undergoing a graded stress test on a cycle ergometer, the subjects were divided into two groups: G1, consisting of athletes with higher aerobic capacity (n = 12; VO2max > 60 ml∙kg−1∙min−1), and G2, comprising athletes with lower aerobic capacity (n = 17; VO2max < 55 mL∙kg−1∙min−1). Heart rate and oxygen uptake recovery was measured after the graded stress test in a sitting position.

Results. HRmax values did not differ significantly between the two groups. HR1’, HR2’, and HR4’ values recorded for G1 were statistically significantly lower compared to those achieved by G2. %HR1’, %HR2’, %HR4’, and %HR5’ values were also significantly lower in G1 than in G2. No significant differences were found in oxygen uptake during recovery (VO2-1’, 2’, 3’, 4’, 5’) between the two groups. Significantly lower %VO2max-1’, %VO2max-2’, and %VO2max-5’ values were observed in G1 compared to those in G2. No significant correlations were found between VO2max per kilogram of body mass and the recovery efficiency index in either group. There was, however, a statistically significant correlation between VO2max and the recovery efficiency index (R = 0.52) in the entire group of athletes (n = 29).

Conclusion. The study showed that the work capacity of mountain bike athletes was associated with the rate of heart rate and oxygen uptake recovery.

A case study on service recovery: Frontline employees’ perspectives and the role of empowerment

Abstract

The aim of this study was to improve our understanding of how frontline employees cope with service recovery situations and recover from them. It also takes a closer look at employee empowerment. This work represents a qualitative case study, and investigates the topic from the perspective of frontline employees. Data collection is implemented by interviewing the case hotel’s frontline personnel. A content analysis method was utilised to analyse the collected data. The findings suggest that the support of colleagues is more crucial in coping with service recovery situations and recovering from them than the support of managers. Personality traits also play a role. A theoretical scheme of the service recovery process from the perspective of frontline employees is developed from the analysis of the interviews. The findings indicate that written instructions would assist employees in service recovery situations.
