BACKGROUND

The Philippines has the highest number of new leprosy cases in the Western Pacific Region, with 1,000 to 2,000+ cases detected annually over the past decade. Out of 46 filariasis-endemic provinces in the country, 43 have eliminated lymphatic filariasis. However, many grade 2 disabilities acquired from these neglected tropical diseases (NTDs) remain undetected due to inadequate monitoring during and after treatment. This was further exacerbated by the detrimental impact of COVID-19 on healthcare access. The pandemic prompted initial adoption of teletraining, making a feasibility study necessary.

This study aimed to determine the feasibility of using telehealth and distance learning to train healthcare workers and patients in the integrated rehabilitation and prevention of impairments and disabilities from leprosy, lymphatic filariasis, mycetoma, diabetes, pressure ulcers, and other chronic wounds.

Selected rural health units, patients with disabilities, and their caregivers in a leprosy- and lymphatic filariasis-endemic region were recruited. Municipal health officers and leprosy coordinators helped in the conceptualization, planning, implementation, and evaluation of the teletraining program to ensure its acceptability and utilization. Asynchronous and synchronous methods were used. The main reference was the "Ten Steps" guide. Training materials were shared via Google Drive and flash drives sent to each study site. One-day didactics and skills trainings were conducted through live-interactive sessions using online platforms (Zoom or Google Meet). Topics focused on nerve function assessment (for leprosy and diabetes), problems of mobility, lymphedema, wound care, and self-care. Participants practiced and demonstrated their skills on local patients, with mentoring through Messenger chats. Knowledge and performance assessments were conducted.

The study was conducted from 2021 to 2022 and the actual training implemented within four months of 2022. Two municipalities of Sultan Kudarat province, Mindanao Island group with one rural health unit (RHU) each had participated. All participants (N=16; eight RHU personnel and eight village health workers) attended the synchronous skills training, 12 (75%) submitted return demo videos, and 13 (81.25%) had practicum patients. All participants rated the training as successfully attaining objectives and activities. All were generally satisfied with the teletraining because of improved knowledge and skills gained and were willing to continue it. Efficiency, speed, quality of training, and trainers had high ratings. Teletraining was considered effective in improving the wound care of their patients. Patients were also satisfied with the home care. However, the unreliable internet service in the study sites created difficulties during synchronous sessions and negatively affected appropriateness of teletraining. Finding patients for practicum was challenging. Some supplies were not available in local drugstores and had to be shipped from Manila, raising costs. Overall, the rating of the teletraining was good.

Teletraining of health workers from distant health units on integrated disability prevention and care is feasible in terms of implementation, acceptability, and practicality if stable internet connectivity is available. Larger studies are recommended.

Necrobiosis lipoidica (NL) is a rare chronic inflammatory granulomatous skin disease, often associated with diabetes mellitus. We present the case of a 52-year-old Filipino female with a history of hypertension and well-controlled diabetes, who developed an ulcerated lesion on her right leg following an insect bite. Despite various self-medications and multiple treatments from different physicians, the ulcer persisted and progressed, leading to her referral for further evaluation. Histopathologic examination confirmed necrobiosis lipoidica. Initial treatment with topical corticosteroids and tacrolimus showed minimal improvement, prompting the use of punch grafting and platelet-rich plasma (PRP) injections. After six PRP sessions, the patient exhibited significant wound healing and a notable reduction in pain, leading to an improved quality of life. This case highlights the effectiveness of punch grafting and PRP injections in managing ulcerated NL, providing a novel therapeutic approach for a challenging condition.

Diabetic ulcer(DU) is a chronic and refractory ulcer which often occurs in the foot or lower limbs. It is a diabetic complication with high morbidity and mortality. The pathogenesis of DU is complex, and the therapies(such as debridement, flap transplantation, and application of antibiotics) are also complex and have long cycles. DU patients suffer from great economic and psychological pressure while enduring pain. Therefore, it is particularly important to promote rapid wound healing, reduce disability and mortality, protect limb function, and improve the quality of life of DU patients. By reviewing the relevant literatures, we have found that autophagy can remove DU wound pathogens, reduce wound inflammation, and accelerate ulcer wound healing and tissue repair. The main autophagy-related factors microtubule-binding light chain protein 3(LC3), autophagy-specific gene Beclin-1, and ubiquitin-binding protein p62 mediate autophagy. The traditional Chinese medicine(TCM) treatment of DU mitigates clinical symptoms, accelerates ulcer wound healing, reduces ulcer recurrence, and delays further deterioration of DU. Furthermore, under the guidance of syndrome differentiation and treatment and the overall concept, TCM treatment harmonizes yin and yang, ameliorates TCM syndrome, and treats underlying diseases, thereby curing DU from the root. Therefore, this article reviews the role of autophagy and major related factors LC3, Beclin-1, and p62 in the healing of DU wounds and the intervention of TCM, aiming to provide reference for the clinical treatment of DU wounds and subsequent in-depth studies.

Diabetic ulcer(DU) is one of the common complications of diabetes often occurring in the peripheral blood vessels of lower limbs or feet with a certain degree of damage. It has high morbidity and mortality, a long treatment cycle, and high cost. DU is often clinically manifested as skin ulcers or infections in the lower limbs or feet. In severe cases, it can ulcerate to the surface of tendons, bones or joint capsules, and even bone marrow. Without timely and correct treatment, most of the patients will have ulceration and blackening of the extremities. These patients will not be able to preserve the affected limbs through conservative treatment, and amputation must be performed. The etiology and pathogenesis of DU patients with the above condition are complex, which involves blood circulation interruption of DU wound, poor nutrition supply, and failure in discharge of metabolic waste. Relevant studies have also confirmed that promoting DU wound angiogenesis and restoring blood supply can effectively delay the occurrence and development of wound ulcers and provide nutritional support for wound healing, which is of great significance in the treatment of DU. There are many factors related to angiogenesis, including pro-angiogenic factors and anti-angiogenic factors. The dynamic balance between them plays a key role in angiogenesis. Meanwhile, previous studies have also confirmed that traditional Chinese medicine can enhance pro-angiogenic factors and down-regulate anti-angiogenic factors to promote angiogenesis. In addition, many experts and scholars have proposed that traditional Chinese medicine regulation of DU wound angiogenesis in the treatment of DU has broad prospects. Therefore, by consulting a large number of studies available, this paper expounded on the role of angiogenesis in DU wound and summarized the research advance in traditional Chinese medicine intervention in promoting the expression of angiogenic factors [vascular endothelial growth factor(VEGF), fibroblast growth factor(FGF), and angiopoietin(Ang)] which played a major role in promoting wound angiogenesis in the treatment of DU to provide ideas for further research and new methods for clinical treatment of DU.

In the orthodontics process, intervention and sliding of an orthodontic bracket during the orthodontic process can arise large response of the labio-cheek soft tissue. Soft tissue damage and ulcers frequently happen at the early stage of orthodontic treatment. In the field of orthodontic medicine, qualitative analysis is always carried out through statistics of clinical cases, while quantitative explanation of bio-mechanical mechanism is lacking. For this purpose, finite element analysis of a three-dimensional labio-cheek-bracket-tooth model is conducted to quantify the bracket-induced mechanical response of the labio-cheek soft tissue, which involves complex coupling of contact nonlinearity, material nonlinearity and geometric nonlinearity. Firstly, based on the biological composition characteristics of labio-cheek, a second-order Ogden model is optimally selected to describe the adipose-like material of the labio-cheek soft tissue. Secondly, according to the characteristics of oral activity, a two-stage simulation model of bracket intervention and orthogonal sliding is established, and the key contact parameters are optimally set. Finally, the two-level analysis method of overall model and submodel is used to achieve efficient solution of high-precision strains in submodels based on the displacement boundary obtained from the overall model calculation. Calculation results with four typical tooth morphologies during orthodontic treatment show that: ① the maximum strain of soft tissue is distributed along the sharp edges of the bracket, consistent with the clinically observed profile of soft tissue deformation; ② the maximum strain of soft tissue is reduced as the teeth align, consistent with the clinical manifestation of common damage and ulcers at the beginning of orthodontic treatment and reduced patient discomfort at the end of treatment. The method in this paper can provide reference for relevant quantitative analysis studies in the field of orthodontic medical treatment at home and abroad, and further benefit to the product development analysis of new orthodontic devices.

PURPOSE: To identify risk factors for developing pressure ulcers (PUs) in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries (SCIs). METHODS: Data were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran (NSCIR-IR) from individuals with traumatic spinal fractures with or without SCIs, inclusive of the hospital stay from admission to discharge. Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay. The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification. In addition to PU, following data were also extracted from the NSCIR-IR datasets during the period of 2015 - 2021: age, sex, Glasgow coma scale score at admission, having SCIs, marital status, surgery for a spinal fracture, American Spinal Injury Association impairment scale (AIS), urinary incontinence, level of education, admitted center, length of stay in the intensive care unit (ICU), hypertension, respiratory diseases, consumption of cigarettes, diabetes mellitus and length of stay in the hospital. Logistic regression models were used to estimate the unadjusted and adjusted odds ratio (OR) with 95% confidence intervals (CI). RESULTS: Altogether 2785 participants with traumatic spinal fractures were included. Among them, 87 (3.1%) developed PU during their hospital stay and 392 (14.1%) had SCIs. In the SCI population, 63 (16.1%) developed PU during hospital stay. Univariate logistic regression for the whole sample showed that marital status, having SCIs, urinary incontinence, level of education, treating center, number of days in the ICU, age, and Glasgow coma scale score were significant predictors for PUs. However, further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center, marital status, having SCIs, and the number of days in the ICU. For the subgroup of individuals with SCIs, marital status, AIS, urinary incontinence, level of education, the treating center, the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis. After adjustment in the multivariate model, the treating center, marital status (singles vs. marrieds, OR = 3.06, 95% CI: 1.55 - 6.03, p = 0.001), and number of days in the ICU (OR = 1.06, 95% CI: 1.04 - 1.09, p < 0.001) maintained significance. CONCLUSIONS These data confirm that individuals with traumatic spinal fractures and SCIs, especially single young patients who suffer from urinary incontinence, grades A-D by AIS, prolonged ICU stay, and more extended hospitalization are at increased risk for PUs; as a result strategies to minimize PU development need further refinement.
