Sufficiency for PSS tracking gait disorders in multiple sclerosis: A managerial perspective.

This study primarily aimed to explore the capabilities of digitalisation in the healthcare context, focusing on a specific disease. In this case, the study examined the potential of remote monitoring of gait to address the sensitivity of multiple sclerosis progression to gait characteristics by adopting a non-invasive approach to remotely quantify gait disturbances in a patient's daily life. To better understand the managerial aspects associated with this approach, the researchers conducted a literature review along with a set of semi-structured interviews. The target population included MS patients as well as the key agents involved in their care: patients' family members, neurologists, MS nurses, physiotherapists, medical directors, and pharmacist. The study identifies the perceived barriers and drivers that could contribute to the successful deployment of PSS remote gait monitoring as a healthcare service: i) At mega-level governance. Implications on privacy and security data are notable barriers missing on the speech. ii) At macro level, funding is highlighted as main barrier. The cost and lack of health system subsidies may render initiatives unsustainable, as emphasised by the interviewees. iii) At meso level, useable data is recognised as a driver. The data collection process can align with diverse interests to create value and business opportunities for the ecosystem actors, enhance care, attract stakeholders, such as insurers and pharma, and form partnerships. iv) At micro-level processes, we find two potential barriers: wearable device and app usability (comfort, navigation, efficiency) and organisational/behavioural aspects (training, digital affinity, skills), which are crucial for value creation in innovation ecosystems among patients and healthcare professionals. Finally, we find an interesting gap in the literature and interviews. Stakeholders' limited awareness of technological demands, especially from information technologies, for a successful long-term service, can be consider two key barriers for PSS.

Compared Block Periodized and Non-Periodized Physical Activity Programs in Older Adults.

BACKGROUND: The periodization of physical exercise to optimize objectives is common in competitive sports. However, physical exercise programs for older adults only sometimes present periodization in their programming. Therefore, this article aims to research the results of applying the sports periodized method to older adults. METHODS: A total of 137 participants over 60 years old performed a physical exercise program; 71 participated in a multi-component non-periodized program as the Control Group (CG), and 66 participated in a program periodized in blocks as the Experimental Group (EG). The block periodization program was oriented to the development of strength and was carried out in 86 sessions thrice weekly for eight months. Anthropometric assessments were made using weight, height, Body Mass Index, and electrical bioimpedance; and functional evaluations were made through standardized tests: Short Performance Physical Battery (SPPB), Timed Up & Go (TUG), handgrip, and a two-minute stair test. RESULTS: After the intervention, the EG significantly improved TUG, weight, and BMI. On the other hand, the CG showed significant improvements in fat weight, BMI, and the 2 min stair test. The SPPB did not show changes after the intervention. CONCLUSION: The periodization of physical exercise for older adults does not significantly impact functional capacity in this population group.

Thoracic lipoblastoma in a 6-year-old African male: a case report.

Lipoblastoma is a very infrequent tumor, characteristic of early childhood. The thoracic location is infrequent, with isolated reports to date. We present the case of a 6-year-old male patient with a right thoracic tumor of months of evolution that was surgically removed by right anterolateral thoracotomy and in which the diagnosis of classic well-differentiated lipoblastoma was histologically confirmed. The patient evolved favorably and was discharged. He is currently under follow-up and without recurrence 1 year after surgery. This is, to our knowledge, the first thoracic lipoblastoma reported in an African pediatric patient. The importance of knowing the clinical, semiological, and intraoperative characteristics of this tumor becomes even more important, as in our case, in the context of international cooperation, where in many cases, there is no possibility of performing pre-operative imaging studies or subsequent genetic studies.

El lipoblastoma es un tumor muy infrecuente, característico de la primera infancia. La localización torácica es infrecuente, con reportes aislados hasta la fecha. Presentamos el caso de un paciente varón de 6 años con una tumoración torácica derecha de meses de evolución que fue extirpada quirúrgicamente mediante toracotomía anterolateral derecha y en la que se confirmó histológicamente el diagnóstico de lipoblastoma clásico bien diferenciado. El paciente evolucionó favorablemente y fue dado de alta. Actualmente se encuentra en seguimiento y sin recidiva un año después de la cirugía. Este es, hasta donde sabemos, el primer lipoblastoma torácico reportado en un paciente pediátrico africano. La importancia de conocer las características clínicas, semiológicas e intraoperatorias de este tumor cobra aún más importancia, como en nuestro caso, en el contexto de la cooperación internacional, donde en muchos casos no existe la posibilidad de realizar estudios de imagen preoperatorios ni estudios genéticos posteriores.

From Aviation to Pediatric Surgery.

Aviation is a tremendously complex process involving multiple factors that can be subsidiary to human error. The implementation of checklists, tools that reduce this risk, has often been extrapolated to other fields, especially medicine. Through this reflection, we comment on the critical and relevant aspects of pediatric surgical patient safety, briefly discussing the existing literature and analyzing potential areas for improvement.

Post-Operative Increase in Serum Interleukin-6 Is Associated With Longer Hospital Stay in Children Operated on for Acute Appendicitis: A Pilot Study.

Background: Pediatric acute appendicitis (PAA) involves a substantial consumption of health and economic resources. The identification of serum biomarkers that may help predict the post-surgical evolution of these patients is a field of great interest. Patients and Methods: This was a prospective, observational substudy within the Biomarkers for the Diagnosis of Appendicitis in Pediatrics (BIDIAP) cohort aimed at evaluating the association between post-surgical increase in serum IL-6 and different outcomes related to the clinical evolution of children operated on for PAA. Sixty-nine children with a confirmed diagnosis of acute appendicitis and both pre-operative and post-operative serum IL-6 were included in the study. Three multivariable-adjusted linear regression models were fitted to analyze the association between an increase of >10% in post-operative serum IL-6 level with the length of stay, the number of post-operative emetic episodes, and the onset of oral feeding. Two multivariable-adjusted logistic regression models were fitted to assess the association of the same exposure with the indication of antibiotherapy at discharge and with positivity in peritoneal fluid culture. Results: Thirteen children showed an increase of >10% in the post-operative serum IL-6 value (group 1) whereas 56 showed only a minor increase, or no change (group 2). After accounting for potential confounders, children in group 1 had a mean of three-day longer hospital stay (difference, 3.33; 95% confidence interval [CI], 0.57-6.09) and higher odds of a positive result in peritoneal fluid culture (odds ratio [OR], 37.43; 95% CI, 1.02-1361.28) than children in group 2. Conclusions: An increase of >10% in post-operative serum IL-6 value could predict longer hospital stay and higher odds of positive peritoneal fluid culture. Future prospective studies are needed to replicate these findings and to broaden the range of biomarkers that could predict the post-operative evolution of children operated on for PAA.

Desarrollo y aplicación clínica de nuevo sistema de tracción cenital esternal en la toracoplastia percutánea videoasistida / Development and clinical application of a new sternal zenithal traction system in video-assisted percutaneous thoracoplasty

Introducción: La toracoplastia percutánea videoasistida implica un acceso quirúrgico complejo y con riesgo de dañar estructuras vitales durante el procedimiento. Históricamente se han aplicado distintos sistemas de tracción y elevación esternal durante la intervención con el fin de minimizar el riesgo asociado al paso del instrumental entre el esternón y el pericardio. Métodos: Se presenta mediante una descripción ilustrada un nuevo sistema de tracción esternal. Se extrajeron los datos clínicos y sociodemográficos de los 36 pacientes intervenidos en nuestro centro de Pectus Excavatum entre julio 2017 y agosto 2021. Todos los pacientes fueron intervenidos por el mismo cirujano. Se clasificó a los pacientes en función de si se había empleado el sistema de tracción esternal (TE) o no (ST). La asignación a uno u otro grupo de intervención se hizo siguiendo un criterio cronológico, sin aplicar el índice de Haller u otro índice. El análisis estadístico de los datos recogidos se realizó con STATA, versión 15.0 (StataCorp). Resultados: La distribución de las variables sociodemográficas muestra que no había diferencias significativas entre los grupos. En 25 de los pacientes se empleó el sistema TE y en 11 no se utilizó ningún ST. El Índice de Haller fue de 4,19±0,7 para el grupo TE y de 3,79±0,3 para el ST. El tiempo quirúrgico medio en minutos fue 88,13±18,1 para el grupo TE y 97,73±46,2 para el grupo ST (p=0,87). La media de días de ingreso fue 7,67±0,8 y 7,73±1,3 para el grupo TE y ST respectivamente. La media de días de PCA intravenosa fue 6,08±0,7 para el grupo TE y 5,89±1,5 para el ST. La media de días de PCA epidural fue 3,79±0,5 y de 3,36±0,5 para el grupo TE y ST respectivamente (p=0,01). Todos los pacientes presentaron una evolución postoperatoria favorable. Ninguno de los pacientes presentó molestias a nivel de las heridas esternales durante el ingreso en hospitalización. La evolución cosmética fue favorable en todos los pacientes. (AU)

Introduction: Video-assisted percutaneous thoracoplasty involves a complex surgical access with risk of damaging vital structures during the procedure. Historically, different traction and sternal elevation systems have been applied during the intervention to minimize the risk associated with the passage of the instruments between the sternum and the pericardium. Methods: A new sternal traction system is presented by means of an illustrated description. Clinical and sociodemographic data were extracted from the 36 patients operated in our center for Pectus Excavatum between July 2017 and August 2021. The Haller index was not applied as a criterion to determine the use or not of the sternal traction system. Patients were classified according to whether the sternal traction system (TE) or not (ST) had been employed. Statistical analysis of the data collected was performed with STATA, version 15.0 (StataCorp). Results: Both groups were comparable. In 25 of the patients the described traction system was used, and in 11 no traction system was used. Haller's index was 4.19±0.7 for the TE group and 3.79±0.3 for the ST group. All patients were operated on by the same surgeon. The mean operative time in minutes was 97.73±46.2 for the ST group and 88.13±18.1 for the TE group (P=.87). The mean total days of admission was 7.67±0.82 (TE) and 7.73±1.35 (ST). Mean days of intravenous PCA was 6.08±0.72 (TE) and 5.89±1.45 (ST). The mean number of epidural PCA days was 3.79±0.5 (TE) and 3.36±0.5 (ST) (P=.01). All patients presented a favorable postoperative evolution. None of the patients presented discomfort at the level of the sternal wounds during hospitalization. Cosmetic evolution was favorable in all patients. (AU)

The BIDIAP index: a clinical, analytical and ultrasonographic score for the diagnosis of acute appendicitis in children.

BACKGROUND: Pediatric acute appendicitis (PAA) continues to be a diagnostic challenge today. The diagnostic performance of classical indices is only moderate, especially in pediatric population. This study aimed to define a clinical, radiological and analytical index for the diagnosis of PAA. MATERIALS AND METHODS: This prospective study included 151 patients divided into two groups: (1) 53 patients with non-surgical abdominal pain (NSAP) and (2) 98 patients with a confirmed PAA. Sociodemographic and clinical characteristics were compared between groups using the Mann-Whitney U test and the Fisher exact test. To identify the predictors of PAA, we performed a multivariable logistic regression using a forward stepwise analysis and we assigned multiples of integer values to the selected variables. The diagnostic performance of the index was assessed by calculating the area under the receiver operating characteristic curve. Intra-cohort calibration was assessed with the Hosmer-Lemeshow test. RESULTS: We developed the BIDIAP index (BIomarkers for the DIagnosis of Appendicitis in Pediatrics), which included three variables that independently predicted higher odds of PAA: appendiceal caliber (≥ 6.9 mm), systemic immune-inflammation index (≥ 890) and peritoneal irritation, which scored 4, 3 and 2 points, respectively. Mean (SD) score of the participants was 2.38 (2.06) in group 1 and 7.89 (1.50) in group 2. The area under the ROC was 0.97 (95% CI 0.95-0.99). The cut-off point was established at 4 points, resulting in a sensitivity of 98.98% and a specificity of 77.78%. CONCLUSIONS: The BIDIAP index has an exceptional diagnostic performance in PAA. The importance of these results lies in its novelty and in the simplicity of the index. Although external validation will be necessary, initial results look promising.

Coagulation Profile: Alterations and Diagnostic Yield in Pediatric Acute Appendicitis: A Prospective Validation Study.

Background: The literature regarding alterations in the coagulation profile in pediatric acute appendicitis (PAA) is scarce and mainly limited to retrospective studies. Evidence on the diagnostic yield of coagulation parameters is limited to fibrinogen. Patients and Methods: This is a prospective study with 151 patients divided into two groups: patients with nonsurgical abdominal pain (NSAP) in whom the diagnosis of PAA was excluded (n = 53) and patients with a confirmed diagnosis of PAA (n = 98). In 93 patients (62%), a coagulation study was obtained at the time of diagnosis and international normalized ratio (INR), activated partial thromboplastin time (aPTT), d-dimer, platelets, mean platelet volume, and platelet-to-lymphocyte ratio were analyzed. The PAA group was further classified into complicated (n = 19) and non-complicated PAA (n = 40). Quantitative variables were compared between groups using the Mann-Whitney U test. Diagnostic performance of the coagulation profile was evaluated with the area under the receiver operating characteristic (ROC) curves. Results: Patients with NSAP had lower median levels of INR, fibrinogen and d-dimer than those with PAA. Moreover, patients with complicated PAA had higher median values of INR and fibrinogen. None of the patients needed specific treatment for the correction of coagulopathy. Fibrinogen was the parameter with the highest diagnostic yield for distinguishing between NSAP and PAA (area under the curve [AUC], 0.74; 95% confidence interval [CI], 0.65-0.85), as well as between complicated versus non-complicated PAA (AUC, 0.71; 95% CI, 0.57-0.86). Conclusions: This study found a moderate extrinsic pathway coagulopathy in patients with PAA, especially in complicated PAA. Fibrinogen is a parameter with moderate diagnostic yield for the diagnosis of PAA.

A New Post-Processing Proposal for Improving Biometric Gait Recognition Using Wearable Devices.

In this work, a novel Window Score Fusion post-processing technique for biometric gait recognition is proposed and successfully tested. We show that the use of this technique allows recognition rates to be greatly improved, independently of the configuration for the previous stages of the system. For this, a strict biometric evaluation protocol has been followed, using a biometric database composed of data acquired from 38 subjects by means of a commercial smartwatch in two different sessions. A cross-session test (where training and testing data were acquired in different days) was performed. Following the state of the art, the proposal was tested with different configurations in the acquisition, pre-processing, feature extraction and classification stages, achieving improvements in all of the scenarios; improvements of 100% (0% error) were even reached in some cases. This shows the advantages of including the proposed technique, whatever the system.

Cooperation and Scientific Contribution: The Search for a Common Nexus.

International cooperation in pediatrics and pediatric surgery entails important barriers such as sociocultural differences, language difficulties, lack of infrastructure and resources, and short duration of campaigns. In this work, we share our personal experience in relation to the scientific publication of works carried out in pediatric international cooperation, and we make a critical reflection on the aspects to be considered for this field to develop in the future.

Effectiveness of the SUGAR intervention on hypoglycaemia in elderly patients with type 2 diabetes: A pragmatic randomised controlled trial.

BACKGROUND: A pharmacist-led, individualised, educational intervention (SUGAR) was formulated to prevent hypoglycaemia among elderly patients with type 2 diabetes mellitus (T2DM) in Jordan. OBJECTIVE(S): To evaluate the effectiveness of the SUGAR intervention added to usual care compared with usual care only in preventing hypoglycaemic attacks in elderly patients with T2DM in Jordan. METHODS: A single-centre, pragmatic, open-label, randomised controlled trial with embedded process evaluation was conducted at the outpatient clinics of a hospital in Jordan. Elderly patients (≥65 years) with T2DM and on sulfonylurea, insulin, or at least three anti-diabetic medications were recruited and parallelly randomised to the SUGAR intervention with usual care or the control (usual care) groups. The primary outcome was the rate of total hypoglycaemic attacks per patient after 3 months from randomisation. Secondary outcomes included rate of hypoglycaemia subtypes, the incidence of any and subtypes of hypoglycaemia, hypoglycaemia-free survival probability, and incidence of fasting hyperglycaemia necessitating therapy modification. Outcomes were measured through glucose meters and diaries, assessed at 3 months, and analysed by intention to treat. RESULTS: A total of 212 participants (mean age 68.98 years, 58.96% men) were randomly allocated (106 in each group), with 190 (89.62%) participants completing the study. The mean of total hypoglycaemic attacks was less in the intervention group compared with the control group (3.91 [SD 7.65] vs. 6.87 [SD 11.99]; p < 0.0001) at three months. The intervention significantly reduced the rate of hypoglycaemia subtypes; the odds to experience any, severe, and symptomatic hypoglycaemia; and increased hypoglycaemia-free survival probability compared with the control group at three months. Incidence of fasting hyperglycaemia necessitating therapy modification was similar between groups. CONCLUSIONS: The SUGAR intervention can prevent hypoglycaemia without increasing the risk of fasting hyperglycaemia warranting therapy adjustment in elderly Jordanians with T2DM.

Congenital Prepubic Sinus as a Variant of Incomplete Urethral Dorsal Duplication: A Case Report with New Insights into its Immunohistochemical Characterization and a Comprehensive Literature Review.

Congenital prepubic sinus (PS) is an extremely infrequent malformation consisting of a prepubic fistulous tract that classically does not communicate with the genitourinary system. Previous studies centered on its immunohistochemical characterization have shown inconsistent results, and the etiology has not been clarified. We present the case of a 2-year-old male who presented since birth with a fistulous orifice on the dorsum of the penis. He had no associated symptoms. Under general anesthesia, the fistulous tract was explored, and methylene blue was instilled through it. After cystoscopically verifying the absence of communication with the urethra, a complete resection of the lesion was performed. The immunohistochemical study showed positivity for low and high molecular weight keratins and a transitional pattern for keratin 7 and GATA3, with positivity at cul de sac level and negativity at proximal level. These findings suggest that this lesion is an incomplete dorsal duplication variant.

Unilateral Anophthalmia and Congenital Frontal Cranioschisis Associated with Extradural Neuroglial Heterotopia: new Insights into a Possible New Malformative Spectrum.

Background: Neuroglial heterotopia, characterized by mature -neuroglial tissue outside the central nervous system, has not been previously associated with cranioschisis. Case Report: A 4-year-old female patient, with left congenital anophthalmia, had a nasofrontal neuroglial heterotopia protruding through an ossification defect. Discussion: Nasofrontal cranioschisis may be associated with neuroglial heterotopias. The combination of anophthalmia and neuroglial heterotopia, previously described only once in the literature, may be part of a broader malformation spectrum that has not been properly characterized to date.

Glans Penis Ischemia after Circumcision in a 15-Year-Old Patient Managed with Intravenous Pentoxifylline: A Case Report and a Diagnostic-Therapeutic Guideline Proposal.

Glans ischemia is an extremely infrequent complication characterized by a total or partial compromise in the penile arterial perfusion. A 15-year-old male patient suffered an episode of ischemia in the glans penis post-circumcision 24 h after surgery. Intravenous treatment with continuous perfusion of pentoxifylline was started for 4 days, with favorable evolution. Complete resolution was observed with no sequelae. There is no consensus on the best therapeutic management. The favorable evolution reported in most of the cases despite different therapeutic approaches leads us to think that the role of the treatments proposed so far is probably less than we believe. Additionally, we present a proposal for a diagnostic and therapeutic guide for this entity. Although the evidence in the literature is scarce and this guideline should be interpreted with caution, we believe that it can constitute a support resource for cases similar to ours.

Extensive Keloid and Hypertrophic Mixed Scarring Pattern in Ear Lobes of a 14-Year-Old African Female: A Case Report.

Background Massive earlobe scarring/keloid formation can occur after ear piercing in individuals of African descent. Case report: A 14-year-old African girl with pierced ears in childhood presented with two progressively growing and disfiguring tumors on both earlobes. The maximum diameter of each lesion was 5.5 centimeters, and the weight of each lesion was approximately 20 grams. Histologically, there was a mixed pattern of keloid and hypertrophic scarring. Discussion: Massive keloids can occur after ear piercing in childhood. It is unclear why some individuals develop these massive keloids.
