RESUMEN

Introduction: Musculoskeletal ailments exert a significant impact on global populations. To address challenges posed by geographical constraints and financial limitations, physiotherapists have explored and found telerehabilitation to be a viable solution. Despite its proven effectiveness in clinical practice, the integration of telerehabilitation has been sluggish. This cross-sectional survey sought to delve into the perspectives and readiness of physiotherapists in Malaysia regarding telerehabilitation for musculoskeletal disorders. Methods: A customized survey instrument was developed and evaluated for face validity and reliability. The 36-item questionnaire was distributed through the Google Form platform, targeting respondents via social media channels such as Facebook and WhatsApp. Data analysis used descriptive statistics (frequency and percentage). Results: The survey garnered responses from 271 physiotherapists. A majority (76.3%, n = 202) expressed agreement regarding the potential benefits of telerehabilitation in physiotherapy practice. About 77% of the respondents also showcased greater readiness for monitoring client progress through telerehabilitation as opposed to assessment and treatment. Notable benefits identified by respondents included preventing cross-infection (98.5%) and reducing travel time for both clients (94.0%) and physiotherapists (90.6%). Conclusion: The study reveals that physiotherapists in Malaysia exhibit positive attitudes and preparedness for implementing telerehabilitation in managing musculoskeletal conditions.

RESUMEN

BACKGROUND: The growing use of telerehabilitation within the healthcare community has garnered substantial attention. In congruence with other healthcare fields, examining perceptions, barriers, and facilitators assumed paramount significance in the continuation and fortification of telerehabilitation practices among physiotherapists. OBJECTIVE: In this scoping review, we aimed to systematically map the literature on the perceptions of physiotherapists as well as the barriers and enablers of telerehabilitation in their daily practice. METHODS: The five-stage methodological framework recommended by Arksey and O'Malley (2005) was used for this scoping review. In the framework, eight databases were searched using key search terms such as "telerehabilitation", "physiotherapists", "readiness", "enablers" and "barriers" All findings were organised into perceptions and readiness, enablers, and barriers. RESULTS: Fourteen articles met the inclusion criteria and were categorized as: (1) perception and readiness, (2) enablers, and (3) barriers. In the perception and readiness category, new trends in healthcare, advancement in physiotherapy practices and the benefits to clients were identified. The enablers identified included prior training, personal experience, familiarity with technology, functional equipment and space, and client selection. The barriers to the adoption of telerehabilitation in physiotherapy practice are pinpointed to poor technology, communication hurdles, limited availability, lack of familiarity, and client-related concerns. CONCLUSION: While initial evidence suggests a generally positive perceptions it is important to consider both facilitators and barriers when understanding adoption. This review's findings revealed a wide research gap, with unequal weightage towards barriers compared to enablers, and highlights the need for further research. Developing telerehabilitation guidelines that cater to both physiotherapists and clients is necessary.

RESUMEN

Objective: This study explored the perceived benefits, barriers, and recommendations of telerehabilitation for musculoskeletal disorders among physiotherapists in Malaysia. Methods: This study employed an exploratory qualitative methodology to gather the perceptions of government-employed physiotherapists in Malaysia regarding the benefits, barriers, and recommendations for telerehabilitation in treating musculoskeletal disorders. The researchers conducted semistructured focus group discussions (FGDs) via Google Meet, which were recorded, transcribed, and analyzed using thematic analysis. Results: Five FGDs were conducted with 24 participants, 37.5% of whom had prior experience with telerehabilitation. The data analysis returned three main themes: (1) perceived benefits, (2) barriers, and (3) recommendations. Four subthemes were derived from perceived benefits: (1a) saving time and money, (1b) convenience, (1c) clients responsible for their treatment, and (1d) alternatives for infectious diseases. Perceived barriers revealed three subthemes: (2a) technology, (2b) organization, and (2c) personal barriers. Finally, participants provided recommendations for improving telerehabilitation services, including training programs to facilitate greater acceptance of this modality. Conclusion: The findings of this study offer crucial insights into the evolving landscape of telerehabilitation in Malaysia. These findings revealed a greater prevalence of barriers to enablers among Malaysian physiotherapists, potentially influenced by varying experience levels. Despite the prevailing lack of experience among participants, this research underscores the significance of identifying barriers and enablers in implementing telerehabilitation with participants offering recommendations for integrating telerehabilitation into their practices. This study provides clear insights and a roadmap for stakeholders aiming to shape the future of telerehabilitation among physiotherapists in Malaysia.

RESUMEN

This cross-sectional study explores caregivers' perceptions of feeding/eating difficulties in persons living with dementia, their support provisions, and the associated burdens. Cognitive decline, behavioral symptoms, and physical issues contribute to the deterioration of feeding/eating activities in people with dementia. Inadequate support during mealtimes has adverse consequences. This study includes 31 caregivers who completed an online questionnaire with three sections: sociodemographic information, feeding/eating problems and required support for individuals with dementia, and caregiver burden and distress. The questions on feeding and eating problems were adapted from the Appetite and Eating Habits Questionnaire (APEHQ). The results show that nearly all persons living with dementia had symptoms of feeding/eating problems, requiring caregiver support, ranging from verbal assistance to full physical assistance. The caregivers reported high distress, which was positively correlated with dementia severity. The findings emphasize the importance of raising caregiver awareness about dementia's impact on eating behavior, identifying effective mealtime care strategies, meeting nutritional needs, and emphasizing personal self-care. This research provides insights for healthcare professionals to develop targeted interventions, alleviate caregiver burden, improve mealtime experiences, and ensure adequate nutrition for persons living with dementia.

RESUMEN

Background: Individuals with severe cerebral palsy (CP) often experience various health issues, including feeding difficulties, which can adversely affect their nutritional status and caregivers' quality of life, e.g., more time spent for feeding rather than own selfcare. This study aimed to determine the prevalence of poor nutritional status among individuals with severe CP and explore its role as predictors for caregivers' quality of life. Methods: This cross-sectional study was conducted in a government hospital (Cheras Rehabilitation Hospital), Community-Based Rehabilitation (CBR) Program, and Spastic Centre [non-profit organization (NGO)] in Klang Valley, Malaysia. Seventy-one participants with Gross Motor Function Classification System (GMFCS) level IV and V were recruited. Sociodemographic data, health-associated data, and anthropometric data were collected. Caregivers' quality of life was assessed using the Pediatric Quality of Life Inventory (PedsQL) CP module version 3.0 which included domains such as Movement and Balance, Eating Activities, and School Activities. Results: Most participants were males (60.6%), with 61 classified as level IV in the GMFCS classification. According to the Eating and Drinking Ability Classification System (EDACS), 59 children were at level IV. In total, 40.8% were underweight according to CP growth chart and 49.3% had mid-upper arm circumference (MUAC) readings below the 5th percentile. The lowest scores in the PedsQL CP module version 3.0 were observed in the Daily Activities (5.34±10.87), and School Activities domains (8.15±18.65). Sociodemographic and anthropometric data, including body mass index (BMI)-for-age, MUAC, body fat, triceps, and subscapular skinfold measurement, were predictors for the School Activities domain [F (11, 44)=3.981, P<0.005, R2=0.499]. Conclusions: Poor nutritional status in individuals with severe CP has been shown to negatively impact caregivers' quality of life. Therefore, a multidisciplinary approach involving nutritional intervention is essential to improve dietary provision and the nutritional status of children with CP.

RESUMEN

The Life Story Book has been commonly used in promoting person-centred care in older adults, especially for persons with dementia. This involves collecting the life stories and memories of the person living with dementia and compiling them into a book or folder, which is used by staff or family to assist the person recall these memories. Evidence on the use, benefits and influences of the Life Story Book in dementia care is limited. This systematic literature review aimed to collect past reviews and provide a thorough overview of the use, benefits, and impact of the Life Story Book for the person with dementia, the relatives, family, and caregivers. The electronic databases PubMed, Scopus, Science Direct and Web of Science as well as grey literature through Google Scholar were searched to select the relevant studies. Seven studies that meet the inclusion criteria were selected and data synthesised. Findings revealed that the use of the Life Story Book has no specific guidelines and has been described with numerous characteristics and varied implementation methods. The Life Story Book intervention is found to provide positive outcomes for the person with dementia and the carers involved. Six out of the seven studies reported that Life Story Book enhanced communication between persons with dementia, relatives, care staff, and residents. The review extends the current evidence on the usage of the Life Story Book in dementia care and confirms that the use of life stories leads to better care in various settings. However, more research is needed to reveal the potential of the Life Story Book in enhancing communication. Guidelines and training are also required to make the best use of the Life Story Book.

RESUMEN

The public sequence databases are entrusted with the dual responsibility of providing an accessible archive to all submitters and supporting data reliability and its re-use to all users. Genomes from type materials can act as an unambiguous reference for a taxonomic name and play an important role in comparative genomics, especially for taxon verification or reclassification. The National Center for Biotechnology Information (NCBI) collects and curates information on prokaryotic type strains and genomes from type strains. The average nucleotide identity (ANI)-based quality control processes introduced at NCBI to verify the genomes from type strains and improve related sequence records are detailed here. Using the curated genomes from type strains as reference, the taxonomy of over 1.1 million GenBank genomes were verified and the taxonomy of over 7000 new submissions before acceptance to GenBank and over 1800 existing genomes in GenBank were reclassified.

RESUMEN

Identification of volume status in nephrotic syndrome (NS) is important but clinically challenging. Urinary and serum indices can be helpful in assessing the volume status and so can be inferior vena cava collapsibility index (IVCCI). This study was done to assess the serum and urinary indices in children with nephrotic edema and to correlate them with IVCCI for intravascular volume assessment. Fifty children with nephrotic edema and 47 children in remission were analyzed for blood and urine indices. Volume status was defined as overfilling or underfilling based on the biochemical indices and also by IVCCI. Eighty-four percent individuals among cases and 23% among controls had sodium retention (FENa < 0.5%). Among cases, 54% had primary sodium retention compared to 17% among controls (p = 0.0002). Hypovolemia was observed among 36% cases based on biochemical indices and in 20% cases as per IVCCI. Hypovolemia was significantly associated with low urinary sodium and low serum albumin.

RESUMEN

Individuals with cerebral palsy (CP) frequently present with multiple feeding problems, which may require food texture modification to ensure safe feeding. This review aims to explore the challenges individuals with CP and their caregiver's face and recommend modified food textures to ensure safety and improve the quality of life and nutritional status. A systematic search was carried out through four databases (i.e., EBSCO (Medline), PubMed, Science Direct, and Web of Science) between January 2011 and May 2022. Out of 86 articles retrieved, seven were selected based on keywords and seven other studies through manual search-five cross-sectional studies, two qualitative studies, one correlational study, one mixed method study, one case-control study, two sections of books, and two educational materials. The findings suggest that preparation and intake of food with modified texture play a necessary role in the safety of swallowing in addition to physical, social, and environmental aspects. Safety was found to be the crucial part of the food texture modification provision besides considering the stress of the caregivers and the nutritional status of individuals with CP. Currently, there are no standard guidelines available pertaining to food texture modification. This led to uncertainties in the dietary provision among caregivers, which may lead to undernourishment. Hence, standard guidelines relating to food texture modification that focuses on food preparation and menus with calorie and nutrient information are timely to be developed.

RESUMEN

Lanthanides are important fission products in molten salt reactors, and understanding their structure and that of their mixtures is relevant to many scientific and technological problems including the recovery and separation of rare earth elements using molten salt electrolysis. The literature on molten salts and specifically on LaCl3 and LaCl3-NaCl mixtures is often fragmented, with different experiments and simulations coinciding in their explanation for certain structural results but contradicting or questioning for others. Given the very practical importance that actinide and lanthanide salts have for energy applications, it is imperative to arrive at a clear unified picture of their local and intermediate-range structure in the neat molten state and when mixed with other salts. This article aims to unequivocally answer a set of specific questions: is it correct to think of long-lived octahedral coordination structures for La3+? What is the nature as a function of temperature of networks and intermediate-range order particularly upon dilution of the trivalent ion salt? Is the so-called scattering first sharp diffraction peak (FSDP) for neat LaCl3 truly indicative of intermediate-range order? If so, why is there a new lower-q peak when mixed with NaCl? Are X-ray scattering and Raman spectroscopy results fully consistent and easily described by simulation results? We will show that answers to these questions require that we abandon the idea of a most prominent coordination state for M3+ ions and instead think of multiple competing coordination states in exchange due to significant thermal energy in the molten state.

RESUMEN

Background: Neurodevelopmental abnormalities are common in congenital heart disease (CHD), more so in cyanotic CHDs. Perioperative factors have been known to affect neurodevelopmental outcomes. Aim: We aimed to determine the neurodevelopmental outcomes following open-heart surgery in cyanotic CHD. Methods: In this prospective observational study, eligible infants and children ≤21 months with cyanotic CHD planned for open-heart surgery underwent preoperative neurodevelopmental assessment using Developmental Assessment Scale for Indian Infants (DASII) to look for any motor and/or mental delay. A second neurodevelopmental assessment was performed after 9 months ± 2 weeks of cardiac surgery. Follow-up DASII was conducted through interactive video conferencing in 23 of 60 patients due to COVID-19 pandemic. The univentricular and biventricular repair groups were compared in terms of their neurodevelopmental outcomes. Perioperative factors were compared between neurodevelopmental "delay" and "no delay" groups. Results: Of the 89 children enrolled, preoperative motor and mental delay were present in 29 and 24 children, respectively. Follow-up DASII could be performed in 60 children. At follow-up, motor delay was present in seven and mental delay in four children. Overall, there was a significant improvement in both motor and mental developmental quotient at follow-up. There was no significant difference in either motor or mental domains between univentricular and biventricular groups. Among the perioperative variables, only the postoperative length of stay in intensive care unit was significantly different between neurodevelopmental "delay" and "no delay" groups (P = 0.04). Conclusion: Neurodevelopmental delay occurred substantially among unoperated children with cyanotic CHD. The neurodevelopmental status improved significantly following open-heart surgery among the survivors. Delay was associated with length of stay in intensive care following cardiac surgery.

RESUMEN

Background: Sixty percent of children with nephrotic syndrome have frequently relapsing or steroid-dependent course. Serious infections like peritonitis, cellulitis, pneumonia etc. and anasarca with reduced urine output and complications there of including acute kidney injury and thromboembolism contribute significantly to morbidity and mortality in these children. Methods: Questionnaire-based module to study infectious complications in children with nephrotic syndrome was circulated through survey monkey portal to paediatric nephrologists in our country. Twenty-two responded. Forty percent said that they saw patients with severe infections once a month. Fish bone analysis conducted on such patients reporting to our centre over next 3 months revealed that only 22% regularly monitored urine protein by dipstick. We proposed that reduction in time to report relapse by regularly monitoring urine protein could reduce complications in these children. Six urine protein dipsticks were handed over to patients who presented >7 days since relapse or with severe infection or anasarca in the last 1 year. These children were followed up for the next 1 year and given six more urine dipsticks every 3 months. Results: Twenty-three patients were given urine protein dipsticks. Nine of them had 12 severe complications in the previous 6 months. None had any serious infections/anasarca on follow-up. Sixteen new patients had 14 serious complications in this time. Conclusions: Early detection of relapse by home monitoring of urine protein by dipsticks was effective in significantly reducing the number of patients with severe infections and anasarca with reduced urine output.

RESUMEN

OBJECTIVE: Retrospective case record analysis of children with Neurobehavioral Deterioration associated with Sleep-augmented Epileptiform abnormalities (NDSE). METHODS: Hospital records of children with NDSE (July, 2015 through December, 2016) were analyzed. Children were categorized as: Encephalopathy with electrical status epilepticus in sleep (ESES) if sleep EEG Spike-wave-Index (SWI) was ≥50% and sleep-induced epileptiform activity (SIEA)-related cognitive dysfunction if SWI ≥25% but <50%. Demography, neurobehavior profile (IQ/SQ and behavior using validated psychometric tools), etiology, investigations and treatment details were documented. Outcome assessment was based on three-month follow-up records. RESULTS: Eighteen children with NDSE {12 boys; median age at diagnosis: 7.5 years (IQR: 6-10 years); SIEA (7); ESES (11)} were included. Etiology was structural (23%) and presumed genetic (77%). All children received intravenous-methylprednisolone pulse followed by oral steroids for eight weeks. Electroencephalography of children with SIEA was partly organized with median SWI of 40% (IQR 35, 42), with anterior-predominant epileptiform abnormalities and less apparent secondary synchronization. Children with ESES had a disorganized EEG background with median SWI of 80% (IQR 66, 95). Both SIEA and ESES groups had a similar neurobehavior profile. Behavior scores improved in 6/8 children with ESES and 5/7 in SIEA post steroids. In both the groups, median SWI improved (to <5% in SIEA, 45% in ESES). Mild improvement in IQ/SQ was also noted {SIEA [Median (IQR): 3 (1.6, 4.3)]; ESES [Median (IQR): 3.8 (2.8, 7)]}. CONCLUSION: The study supports the fact that SWI >50% in the nap EEG is not mandatory for the diagnosis of ESES, thus it should not be a constraint for steroid treatment.

RESUMEN

BACKGROUND: Information on the course of SARS-CoV-2 infection in children with chronic kidney disease (CKD) is limited. METHODS: We retrospectively reviewed the presentation and outcomes of SARS-CoV-2 infection in patients with CKD followed at any of the four pediatric nephrology centers in New Delhi from April 2020 to June 2021. Outcomes, including cardiopulmonary and renal complications, were reported in relation to underlying disease category and illness severity at presentation. RESULTS: Underlying illness in 88 patients included nephrotic syndrome (50%), other CKD stages 1-4 (18.2%), CKD 5D (17%), and CKD 5T (14.8%). Thirty-two of 61 patients with symptomatic COVID-19 and 9/27 asymptomatic patients were admitted for median 10 (interquartile range 7-15) days. Seventeen (19.3%) patients developed moderate or severe COVID-19. Systemic complications, observed in 30 (34.1%), included acute kidney injury (AKI, 34.2%), COVID-19 pneumonia (15.9%), unrelated pulmonary disease (2.3%), and shock (4.5%). Nineteen (21.6%) had severe complications (AKI stage 2-3, encephalopathy, respiratory failure, shock). Eight (11%) of twelve (16.4%) patients with severe AKI required dialysis. Three (3.4%) patients, two with steroid-resistant nephrotic syndrome in relapse and one with CKD 1-4, died due to respiratory failure. Univariate logistic regression indicated that patients presenting with nephrotic syndrome in relapse or moderate to severe COVID-19 were at risk of AKI (respective odds ratio, 95%CI: 3.62, 1.01-12.99; 4.58, 1.06-19.86) and/or severe complications (respective odds ratio, 95%CI: 5.92, 1.99-17.66; 61.2, 6.99-536.01). CONCLUSIONS: Children with CKD presenting with moderate-to-severe COVID-19 or in nephrotic syndrome relapse are at risk of severe complications, including severe AKI and mortality. A higher resolution version of the Graphical abstract is available as Supplementary information.

RESUMEN

Objectives: To study the biochemical, metabolic and hormonal profile among children presenting with acne and to determine the correlation of these parameters with acne grading. Methods: The observational cross-sectional study was conducted for a duration of 18 months on a total of 50 children between 1 and 12 years of age with clinical features of acne. The detailed information regarding the type of acne, biochemical profile (lipid profile, blood sugar levels), hormonal profile and associated illnesses were recorded. Spearman's rank correlation coefficient was used to find out the correlation of acne grading with hormonal and metabolic changes. Results: The mean age of the children was 11.4 years. Among the various lesions, comedones were seen in 98% cases, papules in 94.00% cases, a scar in 14.00% and pustule in 4.00% cases. As compared to children of age 1-7 years, those in age group 8-12 years had significantly more comedones (48 vs 1, P = 0.04), significantly fewer pustules (0.00% vs 100.00%, P = 0.001), and a comparable number of papules and scars. Most of the children (88.00%) had acne vulgaris grade 1. There was a significant negative correlation of Blood sugar-fasting (r = -0.312, P = 0.0275) and a significant positive correlation of HDL (r = 0.28, P = 0.0491) with acne grading. Conclusion: Comedones and papules are the commonest and the earliest forms of pediatric acne. Severe forms of acne are rarely seen below 12 years, age group. Preadolescent acne is commoner than mid-childhood acne, with no difference between male and females. Blood sugar levels and lipid profile derangements have a weak correlation with acne grading.

RESUMEN

BACKGROUND: Online learning is an attractive option for educators, especially as means of overcoming the challenges posed by the global pandemic. Although it is best to evaluate student readiness prior to commencement of an online course, to ensure successful development and delivery of student-centric teaching and learning strategies, readiness towards online learning among physiotherapy undergraduates is unknown. The main aim of this study was to examine physiotherapy undergraduates' readiness towards online learning. METHODS: In this cross-sectional study, participants were selected through a combination of total population and convenience sampling. The Student Online Learning Readiness questionnaire was distributed among physiotherapy undergraduates from two public and two private universities in Malaysia to investigate their technical, social and communication competencies. Information about device characteristics were obtained to evaluate their equipment readiness. Descriptive and group comparisons were conducted using independent t-test, and analysis of variance with p < 0.05 as level of significance. RESULTS: A total of 352 physiotherapy undergraduates participated. The response rate was 81.6%. The results showed that physiotherapy undergraduates in these four institutions had moderate levels of readiness towards technical competencies (M = 3.7 ± 0.5), social competencies with instructor (M = 3.7 ± 0.6), social competencies with classmates (M = 3.8 ± 0.6) and communication competencies (M = 3.6 ± 0.5) related to online learning. The overall readiness for these four competencies was moderate (M = 3.7 ± 0.4), however the physiotherapy undergraduates had high (> 80% possessed smartphones and laptop) level of equipment readiness. Institution and gender had no significant effect on the level of readiness (p > 0.05). Year 1 and 2 had significantly higher levels of social competencies with instructor compared to final year physiotherapy undergraduates (p < 0.05). CONCLUSION: Physiotherapy undergraduates in these four institutions had moderate to high levels of readiness towards online learning. Technical, social and communication competencies could be further enhanced with appropriate strategies. SIGNIFICANCE: This study provides an insight into the level of readiness towards online learning among physiotherapy undergraduates. The findings of our study shed light on issues to consider when designing online courses. A pre-course training for undergraduates prior to the commencement of online courses may be useful. TRIAL REGISTRATION: Not Applicable.

RESUMEN

Enhancing the solar energy storage and power delivery afforded by emerging molten salt-based technologies requires a fundamental understanding of the complex interplay between structure and dynamics of the ions in the high-temperature media. Here we report results from a comprehensive study integrating synchrotron X-ray scattering experiments, ab initio molecular dynamics simulations and rate theory concepts to investigate the behavior of dilute Cr3+ metal ions in a molten KCl-MgCl2 salt. Our analysis of experimental results assisted by a hybrid transition state-Marcus theory model reveals unexpected clustering of chromium species leading to the formation of persistent octahedral Cr-Cr dimers in the high-temperature low Cr3+ concentration melt. Furthermore, our integrated approach shows that dynamical processes in the molten salt system are primarily governed by the charge density of the constituent ions, with Cr3+ exhibiting the slowest short-time dynamics. These findings challenge several assumptions regarding specific ionic interactions and transport in molten salts, where aggregation of dilute species is not statistically expected, particularly at high temperature.

RESUMEN

In this work, we resolve a long-standing issue concerning the local structure of molten MgCl2 by employing a multimodal approach, including X-ray scattering and Raman spectroscopy, along with the theoretical modeling of the experimental spectra based on ab initio molecular dynamics (AIMD) simulations utilizing several density functional theory (DFT) methods. We demonstrate the reliability of AIMD simulations in achieving excellent agreement between the experimental and simulated spectra for MgCl2 and 50 mol % MgCl2 + 50 mol % KCl, and ZnCl2, thus allowing structural insights not directly available from experiment alone. A thorough computational analysis using five DFT methods provides a convergent view that octahedrally coordinated magnesium in pure MgCl2 upon melting preferentially coordinates with five chloride anions to form distorted square pyramidal polyhedra that are connected via corners and to a lesser degree via edges. This is contrasted with the results for ZnCl2, which does not change its tetrahedral coordination on melting. Although the five-coordinate MgCl53- complex was not considered in the early literature, together with an increasing tendency to form a tetrahedrally coordinated complex with decreasing the MgCl2 content in the mixture with alkali metal chloride systems, current work reconciles the results of most previous seemingly contradictory experimental studies.
