Patient education in Parkinson's disease: Formative evaluation of a standardized programme in seven European countries

OBJECTIVE: To evaluate a newly developed education programme for Parkinson's disease (PD) patients. METHODS: The programme consisted of eight sessions and aimed at improving knowledge and skills related to self-monitoring, health promotion, stress management, depression, anxiety, social competence, and social support, all with special reference to PD. The programme was formatively evaluated in seven European countries (Spain, Finland, Italy, The Netherlands, United Kingdom, Estonia, Germany) with 151 patients diagnosed with idiopathic PD. The evaluation included patients' ratings of the comprehensibility and feasibility of the programme as well as mood ratings before and after each session. Patients also completed questionnaires at the beginning and end of the programme to explore possible changes in disease-related psychosocial problems, quality of life, and depression. RESULTS: The programme was feasible to run, and patients were able to understand its elements. Patients reported mood elevations following individual sessions and reduced disease-related psychosocial problems after completing the programme. There were no substantial differences in results between cultures. CONCLUSION: Patient education appears to have potential as a useful and feasible intervention, complementing medical treatment in PD. PRACTICE IMPLICATIONS: The present programme will soon be available in seven European languages and can be tested in different health care systems.     

Potential neuroprotective role of astroglial exosomes against smoking-induced oxidative stress and HIV-1 replication in the central nervous system

Introduction: HIV-1-infected smokers are at risk of oxidative damage to neuronal cells in the central nervous system by both HIV-1 and cigarette smoke. Since neurons have a weak antioxidant defense system, they mostly depend on glial cells, particularly astrocytes, for protection against oxidative damage and neurotoxicity. Astrocytes augment the neuronal antioxidant system by supplying cysteine-containing products for glutathione synthesis, antioxidant enzymes such as SOD and catalase, glucose for antioxidant regeneration via the pentose-phosphate pathway, and by recycling of ascorbic acid.

Areas covered: The transport of antioxidants and energy substrates from astrocytes to neurons could possibly occur via extracellular nanovesicles called exosomes. This review highlights the neuroprotective potential of exosomes derived from astrocytes against smoking-induced oxidative stress, HIV-1 replication, and subsequent neurotoxicity observed in HIV-1-positive smokers.

Expert opinion: During stress conditions, the antioxidants released from astrocytes either via extracellular fluid or exosomes to neurons may not be sufficient to provide neuroprotection. Therefore, we put forward a novel strategy to combat oxidative stress in the central nervous system, using synthetically developed exosomes loaded with antioxidants such as glutathione and the anti-aging protein Klotho.     

Hybrid closed-loop therapy: Where are we in 2021?

Hybrid closed-loop systems are characterized by the coexistence of algorithm-driven automated insulin delivery combined with manual mealtime boluses. Used correctly, these insulin delivery systems offer better glucose control and reduced risk of hypoglycaemia and represent the most advanced form of insulin delivery available for people with type 1 diabetes. The aim of this paper was to compare the currently available commercial hybrid closed-loop systems in the UK: the Medtronic 670G/780G, Tandem t:slim X2 Control IQ and CamAPS FX systems. The Medtronic 670G/780G systems use Guardian 3 sensor (7-day use, two to four calibrations per day), while Tandem and CamAPS systems use the calibration-free Dexcom G6 sensor (10 days). The CamAPS system is available as an android app, whereas the other two systems have the algorithm embedded in the insulin pump. During pivotal studies, depending on the study population and baseline glycated haemoglobin level, these systems achieve a time spent in the target range 3.9 to 10 mmol/L (70 to 180 mg/dL) of 65% to 76% with low burden of hypoglycaemia. All three systems allow a higher glucose target for announced exercise, while the Tandem system offers an additional night-time tighter target. The CamAPS system offers fully customizable glucose targets and is the only system licensed for use during pregnancy. Additional education is required for both users and healthcare professionals to harness the best performance from these systems as well as to troubleshoot when “automode exits” occur. We provide consensus recommendations to develop pragmatic pathways to guide patients, clinicians and commissioners in making informed decisions on the appropriate use of the diabetes technology.     

Electrolyte and Haemogram changes post large volume liposuction comparing two different tumescent solutions

Background:

The most common definitions of large volume liposuction refer to total 5 l volume aspiration during a single procedure (fat plus wetting solution). Profound haemodynamic and metabolic alterations can accompany large volume liposuction. Due to paucity of literature on the effect of different tumescent solutions on the electrolyte balance and haematological changes during large volume liposuction, we carried out this study using two different wetting solutions to study the same.

Materials and Methods:

Total 30 patients presenting with varying degrees of localized lipodystrophy in different body regions were enrolled for the study. Prospective randomized controlled trial was conducted by Department of Plastic and Cosmetic Surgery, Sir Ganga Ram Hospital, New Delhi from January 2011 to June 2012. Patients were randomized into two groups of 15 patients each by using computer generated random numbers. Tumescent formula used for Group A (normal saline [NS]) was our modification of Klein''s Formula and Tumescent formula used for Group B (ringer lactate [RL]) was our modification of Hunstadt''s formula. Serum electrolytes and hematocrit levels were done at preinduction, immediate postoperative period and postoperative day 1.

Result:

Statistical analysis was performed using SPSS software version 15.0. Which showed statistically significant electrolytes and hematocrit changes occur during large volume liposuction.

Conclusion:

Statistically significant electrolytes and hematocrit changes occur during large volume liposuction and patients should be kept under observation of anaesthesist for at least 24 h. Patients require strict monitoring of vital parameters and usually Intensive Care Unit is not required. There was no statistical difference in the electrolyte changes using NS or RL as tumescent solution and both solutions were found safe for large volume liposuction.KEY WORDS: Electrolyte changes during liposuction, haemogram changes during liposuction, large volume liposuction     

The Utilization of Quality KPIs in the Pharmaceutical Industry

Purpose

The overall aim of this study was to investigate the significance of quality key performance indicators (KPIs) and how comprehensively they are used in the pharmaceutical industry. A specific aim was to find which KPIs were relevant to personnel from the perspective of their own work responsibilities. A further aim was to determine which factors motivate personnel enough to respond to improve KPIs.

Methods

Qualitative theme interviews of ten staff from one case company were conducted to study the impact of KPIs. Interview data were analyzed using qualitative content analysis and reductive analysis.

Results

Personnel considered deviations in manufacturing and packaging to be the most important quality KPI when they considered their own work responsibilities. The quality indicators data were utilized quite efficiently, for example, in complaint and deviation handling processes, and they provided useful information for corrective and preventive actions (CAPA)-reporting. The most important factors that motivated supervisors, managers, and experts regarding KPIs were those that affected interviewees own particular work responsibilities, the cooperation within the operators own departments, and the cooperation between different departments. The interviewees opined that the production bonus was the most important motivational factor for production operators to improve upon quality indicator performance.

Conclusions

Quality indicator feedback data were utilized widely by the case company and were considered to be a useful tool to guide personnel in ensuring or potentially improving the quality of operations.     

Predictors of mortality in children with typhoid ileal perforation in a Nigerian tertiary hospital

Purpose

Childhood typhoid ileal perforation is associated with high morbidity and mortality. Our aim was to ascertain the predictors of survival in children.

Materials and methods

This is a tertiary hospital-based retrospective review of patients aged ≤15 years managed for typhoid ileal perforations between January 2005 and December 2013. The details of their biodata, potential risk factors and outcome were evaluated.

Results

Forty-five children out of a total of 97 with typhoid fever had typhoid ileal perforation. The age range was 2–15 years, mean (±SD) = 9.3 (±3.31) years, median = 10 years. There were more males than females (26:19). Thirty-nine (86.7 %) patients were >5 years old. There were nine deaths (20 % mortality). The mean (±SD) age of survivors was 9.8 (±2.9) years and 7.1 (±4.2) for non-survivors (p = 0.026). The duration of illness at presentation, gender, admission temperature, nutritional status and packed cell volume, perforation-operation interval, number of perforations, surgical procedure, and the duration of surgery did not statistically influence survival (p > 0.05). The age of the patients and burst abdomen attained statistical significance (p < 0.05).

Conclusion

The patients’ age and postoperative burst abdomen were significant determinants of survival in children with typhoid ileal perforation.
