The rising need for structured and efficient blood transfusion services in low-resource settings has driven the adoption of collaborative blood transfusion management systems (CBTMS). This study explores the functionality and impact of the Cornerstone University Blood Management System version 1.0 (CUBMS vs 1.0) in Cameroon. This study was an exploratory research design which used a system interface analysis, comparative case reviews from four countries, and literature synthesis, to reveal that CUBMS improves accessibility, data management, inventory control, emergency responsiveness, and community engagement. Despite infrastructural challenges in rural regions, the system can enhance efficiency, transparency, and safety in blood services. The success of CBTMS in Cameroon is linked to digital infrastructure, training, and culturally relevant community engagement. The Ministry of Public Health of Cameroon should prioritize the nationwide implementation of CBTMS, ensuring consistency in digital health tools.

The Generalized Electron Balance (GEB) concept, related to electrolytic redox systems, is considered according to principles of Generalized Approach to Electrolytic Systems (GATES). Two equivalent Approaches (I and II) to GEB are presented. The Approach I, when perceived in convention of the card game, is based on the common pool of electrons as money, introduced by electron-active elements, named as players; electron-non-active elements are called there as fans. The GEB obtained according to Approach II results from the linear combination f12 = 2∙f(O) – f(H) of elemental balances: f1 = f(H) for H, and f2 = f(O) for O. Very important properties of f12 are presented here in details, and illustrated by a redox system where comproportion- ation reactions occur

This article has been retracted on 20 January 2022. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2379-8572.joa-25-5850) Back ground and Objectives Tonsillectomy is the most common surgical procedure in specialty of otorhinolaryngology. Therefore there are frequent premises regarding this procedure to be improved from different aspects, indications, time of surgery, techniques, safety measures, and postoperative care. Hence the tonsils and peritonsillar tissues are highly vascular zone that supplied by direct branches of external carotid artery thus the post-tonsillectomy bleeding remains one of significant issues in relation to this widely performed procedure. The post-tonsillectomy bleeding needs frequently to be postulated for its incidence, prevalence, etiology, predisposing factors, management and prevention. This subject constitutes one of most risky aspects that increase wariness of the surgeons regarding this commonly conducted procedure. Although there are huge numbers of presentative literatures coming from American as well as western institutes that tried to put guidelines for purpose of prevention and management of post-tonsillectomy bleeding but broadly at our middle-east region and locally at our Libyan society we found for some extent difficulties to apply all these guidelines. For this reason this issue has been take the wider spectrum of ENT surgeons’ concentration, discussions, and researches. Therefore this study was conducted prospectively and for long time to confirm the possible predisposing factors that could be responsible for increasing the risk of post-tonsillectomy bleeding at our region and in the same time to illustrate the concluded recommendations to prevent the occurrence of this important complication. Patients and Methods 2880 patients aged from 8 months to 85 years presented at ENT department-AL-hawari ENT and urology teaching center- Benghazi-city – Libya as well as AL-thowra central teaching hospital and AL-tarahom private center – Elbyda city – Libya at period in between September 2003 to March 2015 as cases of chronic adeno-tonsillitis and solitary acute as well as chronic related palatine tonsillar disease with variable patterns of indications for tonsillectomy namely snoring and apnea attacks, recurrent attacks of acute tonsillitis, persistent otitis media with effusion, recurrent attacks of acute suppurative otitis media, failure to thrive, recurrent attacks of chest infection, mal-occlusive dental deformity, unilateral enlarged tonsils, post-traumatic avulsed tonsils, history of quinsy abscess and persistent halitosis. All patients were assessed intra-operatively and post-operatively too for any evidences of primary, reactionary, or secondary hemorrhage in relation to wide spectrum of factors as patient's demographic, medical, and socio-habitual factors, in addition to technical as well as post-operative care factors. Results This presenting study confirmed that the most common type of post-tonsillectomy bleeding was the secondary variety (71%) as compared to primary (22%) and reactionary (7%) among all presented post-tonsillectomy bleeding cases. Although through this presenting serial study there were multifactorial pre-dispositions elucidated for secondary post-tonsillectomy hemorrhage but as general poor post-operative care can be considered as the cornerstone for the pathogenesis of this significantly raised incidence of secondary post-tonsillectomy bleeding this may be in form of inadequate patient's hydration and nutritional supply (47%), poor patient's antibiotic compliance (23%), and child's maternal negligence (19%). The time of surgery was found to be another important pre-disposing factor for post-tonsillectomy bleeding, it was postulated that the incidence of reactionary as well as secondary post-tonsillectomy hemorrhage significantly increased at summer and autumn seasons (69%) as compared to other seasons. The place of surgery was another interesting proposed studied factor among this serial presentation it was observed that the incidence of post-tonsillectomy bleeding among patients who operated at AL-hawari ENT and urology teaching center-Benghazi-city significantly higher (63%) than that among cases who interfered at AL-thowra central teaching hospital and AL-tarahom private center – Elbyda city. Conclusion Generally speaking, post-tonsillectomy bleeding is considered as one of important issues in ENT and one of significant post-tonsillectomy complications which may create a critical morbidity that may rarely extend to post-operative mortality. Hence the most common pattern of post-tonsillectomy bleeding is the secondary type; however this type of post-tonsillectomy hemorrhage is pre-disposed and induced by many factors. Most of these factors are treatable and curable thus the prophylaxis against this significant complication can be achievable.

Study Design: Prospective study, simple crossover design. Background: Proprioception is a cornerstone for maintaining joint and postural stability. Dynamic stability is particularly emphasized within these components. This feature is important in the rehabilitation field. Therefore, the quest for elements to improve these values can bring advantages in sports. Objectives: Evaluate if there are advantages in the performance of a Star Excursion Balance Test (SEBT) using Kinesio taping. Methods: We evaluated 10 professional soccer players from the Chilean women’s national team. They were randomly divided into 2 groups. One group had Kinesio taping and their SEBT performance was evaluated. The other group performed the measurements without the use of Kinesio Taping. Afterward, each group performed the evaluation they did not do during the first stage. We then compared the performance achieved with and without the use of Kinesio Taping Results: There were significant differences in the performance achieved by the players who had the SEBT bandage applied in comparison to the players that did no. This was confirmed by using the non-parametric Wilcox test for each of the SEBT positions. Conclusions: Kinesio taping has positive implications in the SEBT. We can extrapolate that its use can improve the dynamic balance and thus become an important pillar in sports rehabilitation.

Background: lifestyle modification is known as the cornerstone for prevention and treatment of chronic diseases. To promote individual’s lifestyle, the first step is to measure their lifestyle by a valid and reliable tool. The aim of present study was to evaluate psychometric properties of the Persian version of Healthy Lifestyle and Personal Control Questionnaire (HLPCQ). Method: A crosssectional study carried out on 300 medical students in Kerman University of Medical Sciences, Iran. Data collected using a questionnaire contained demographic data and Persian version of HLPCQ. The reliability of the questionnaire determined using Cronbach’s alpha and intra class correlation coefficient (ICC). The construct validity of the questionnaire evaluated by exploratory and confirmatory factor analysis. Data were analyzed by SPSS version 19 and Lisrel 8.8. Results: Internal consistency of HLPCQ was 0.78 using Cronbach’s alpha and 0.80 by ICC. In confirmatory factor analysis, the scale had acceptable goodness of fit indices. Conclusions: The Persian version of HLPCQ had excellent psychometric properties and can be used in in primary health care settings.

Objectives: Bariatric surgery has been established as the cornerstone of treatment of morbid obesity with good immediate and long-term results. Nutrient deficiencies though, can be an important long-term complication and may lead to hematological, metabolic and especially neurological disorders which are not always reversible. Thiamine (vitamin B1) deficiency has been reported both after restrictive and malabsorptive procedures. The aim of this study is to review all cases that presented with Wernicke Encephalopathy after sleeve gastrectomy. Methods: A review of the literature was conducted to evaluate all sleeve gastrectomies performed till today and caused Wernicke encephalopathy to the patients. Demographic data, operative parameters, postoperative outcomes were collected and assessed. Results: A total of 13 studies, including 13 patients were analyzed. Patients ranged in age from 17 to 55 years. The onset of Wernicke encephalopathy occurred as early as 3 weeks after surgery to as late as 60 weeks after surgery. When symptoms of Wernicke encephalopathy developed, patients had lost from 19 kg up to 60 kg of body weight. Conclusions: Micronutrient deficiencies and particularly B1 deficiency can occur after LSG, although rarely. Preoperative nutritional assessment and postoperative follow-up plan, should signs of Wernicke’s encephalopathy be traced, is recommended in all patients.
