BACKGROUND

Type 2 diabetes is the most common type of diabetes in the Philippines. Diabetic foot complications represent a prevalent and significant chronic concern for individuals with type 2 diabetes. This poses an immediate community health concern, as diabetic complications may threaten an individual's well-being.

This study intends to cross-culturally adapt the Diabetic Foot Knowledge Subscale (DFKS) and Foot Self-Care Behavior Scale (FSCBS) questionnaires into the Filipino language as an assessment tool among Filipinos with diabetes.

The study employed a psychometric research design, where it entailed Phase A and Phase B. Phase A involved the forward translation of the DFKS and FSCBS questionnaires, followed by the synthesis of the translations and backward translation. Subsequently, an expert committee reviewed the translations and concluded the final version. The final translated versions of the questionnaires ensured that it can be understood by an individual who has a Grade 6 level of reading proficiency. Phase B entailed the validity testing with the evaluation of the expert committee, and reliability testing of the said questionnaires with a sample size of 30 participants. A wash-out period of 24 hours was given for the test-retest reliability, followed by data analysis. The validity and reliability of the questionnaires were measured using the item and scale content validity indices and the internal consistency and test-retest reliability, respectively, to ensure their accuracy and appropriateness. The content validity of the questionnaires was evaluated individually by the experts using a Likert scale from 1-4, with 4 being the highest meaning the item was very relevant and succinct. Scores per item were between 3 and 4, which indicate that the translated version of the items were relevant and succinct or were relevant but needed minor revisions.

The validity scores for the translated DFKS and FSCBS questionnaires were obtained using the Scale Content Validity Index (S-CVI) with a score of 0.96 and 0.92, respectively. Moreover, all items in the questionnaires obtained an Item Content Validity Index (I-CVI) of 0.88-1.00. The DFKS also has an acceptable internal consistency with a Cronbach’s alpha of 0.72, while the FSCBS has a good internal consistency with a Cronbach’s alpha of 0.85. The test-retest reliability shows an acceptable Spearman’s correlation at 0.76 for the DFKS and a strong positive Pearson correlation coefficient at 0.73 for the FSCBS.

The validity of the two questionnaires was acceptable and the test-retest reliability showed a strong positive correlation among the items thereby making the cross-cultural adaptation of the questionnaires successful. The Filipino versions of the DFKS and FSCBS questionnaires accurately measure the knowledge and behavior of individuals with type 2 diabetes, respectively.

OBJECTIVE: To observe the clinical efficacy of wrist-ankle acupuncture in the treatment of functional frequent premature ventricular contractions (PVCs). METHODS: A total of 64 patients with functional frequent PVCs were randomly divided into an observation group and a control group, 32 cases in each group. The observation group was treated with wrist-ankle acupuncture at bilateral upper 1 and upper 2 on the wrist. The control group received sham acupuncture at the same points as the observation group. Both groups were treated once every day from Monday to Friday, with the needles retained for 60 min each time, for a total of 4 weeks. The TCM syndrome score, the 24-hour PVC count, and MOS 36-item short form health survey (SF-36) score were compared between the two groups before and after treatment, and the clinical efficacy was evaluated after treatment. RESULTS: After treatment, the TCM syndrome scores and the 24-hour PVC counts in both groups were reduced compared with those before treatment (P<0.01), and the above indexes in the observation group were lower than those in the control group (P<0.01). After treatment，scores of all SF-36 items in the observation group were increased compared with those before treatment (P<0.01); in the control group, the scores of general health (GH), social function (SF) and role-emotional (RE) were increased compared with those before treatment (P<0.05). After treatment, scores of all SF-36 items in the observation group were higher than those in the control group (P<0.01). The total effective rate in the observation group was 90.6% (29/32), which was higher than 46.9% (15/32) in the control group (P<0.01). CONCLUSION Wrist-ankle acupuncture has a significant clinical efficacy in the treatment of functional frequent PVCs. It can effectively improve symptoms such as chest tightness and palpitations, reduce 24-hour PVC count, and improve patients' quality of life.

BACKGROUND: Diabetic foot is a complex condition with high incidence, recurrence, mortality, and disability rates. Current treatments for diabetic foot ulcers are often insufficient. This study was conducted to identify potential therapeutic targets for diabetic foot. METHODS: Datasets related to diabetic foot and diabetic skin were retrieved from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified using R software. Enrichment analysis was conducted to screen for critical gene functions and pathways. A protein interaction network was constructed to identify node genes corresponding to key proteins. The DEGs and node genes were overlapped to pinpoint target genes. Plasma and chronic ulcer samples from diabetic and non-diabetic individuals were collected. Western blotting, immunohistochemistry, and enzyme-linked immunosorbent assays were performed to verify the S100 calcium binding protein A9 (S100A9), inflammatory cytokine, and related pathway protein levels. Hematoxylin and eosin staining was used to measure epidermal layer thickness. RESULTS: In total, 283 common DEGs and 42 node genes in diabetic foot ulcers were identified. Forty-three genes were differentially expressed in the skin of diabetic and non-diabetic individuals. The overlapping of the most significant DEGs and node genes led to the identification of S100A9 as a target gene. The S100A9 level was significantly higher in diabetic than in non-diabetic plasma (178.40 ± 44.65 ng/mL vs. 40.84 ± 18.86 ng/mL) and in chronic ulcers, and the wound healing time correlated positively with the plasma S100A9 level. The levels of inflammatory cytokines (tumor necrosis factor-α, interleukin [IL]-1, and IL-6) and related pathway proteins (phospho-extracellular signal regulated kinase [ERK], phospho-p38, phospho-p65, and p-protein kinase B [Akt]) were also elevated. The epidermal layer was notably thinner in chronic diabetic ulcers than in non-diabetic skin (24.17 ± 25.60 μm vs. 412.00 ± 181.60 μm). CONCLUSIONS S100A9 was significantly upregulated in diabetic foot and was associated with prolonged wound healing. S100A9 may impair diabetic wound healing by disrupting local inflammatory responses and skin re-epithelialization.

Simiao Yong'an Decoction is derived from the New Compilation of Proved Prescriptions(Yan Fang Xin Bian). This formula has the effects of clearing heat and detoxifying as well as activating blood and relieving pain. It is mainly used to treat gangrene caused by excessive heat toxin and with the clinical manifestations including dark red and slightly swollen limbs, scorching skin, ulceration and odor, severe pain, occasional fever, thirst, red tongue, and rapid pulse. Nowadays, Simiao Yong'an Decoction is mostly used in the treatment of thromboangitis obliterans, ulcers in arteriosclerosis obliterans of lower limbs, stent restenosis after angioplasty of lower limbs, ecthyma, deep venous thrombosis, diabetic arteriosclerosis obliterans of lower limbs, diabetic foot ulcer, acute knee arthritis, varicose veins of lower limbs, coronary heart disease, post percutaneous coronary intervention(PCI), sepsis, gout, tumor, chronic tonsillitis in children, and other diseases. It has been identified that diabetic foot with infection, sepsis, arteriosclerosis obliterans, and thromboangitis obliterans belong to the category of gangrene in traditional Chinese medicine(TCM), and Simiao Yong'an Decoction is an ancient specialized prescription for treating this disease. The diseases that can be treated by Simiao Yong'an Decoction include arteriosclerosis obliterans, thromboangitis obliterans, diabetic foot, and ecthyma. The symptoms that can be treated by Simiao Yong'an Decoction include dark red, blackened, slightly swollen, burning, ulceration, and odor in the fingers and toes, and toes falling off, hands and feet decaying and collapsing, severe and unbearable pain in some cases. Furthermore, this formula is effective for skin ulceration spreading, pus dripping, swollen and proliferating lymph nodes. These symptoms are always accompanied by dry mouth, thirst, irritability, yellow urine, and dry stool. The TCM symptoms include red tongue, thin and white tongue coating, and wiry and rapid pulse. In the case with the complication of refractory hypotension, large dosage of Astragali Radix is used to replenish Qi, reinforce healthy Qi, and expressing toxin, which can often achieve blood pressure-elevating and anti-inflammatory effects. Simiao Yong'an Decoction is often combined with Simiao Pills and Guizhi Fuling Pills. High-dose medication is the key to the effectiveness of this formula. Integrated traditional Chinese and western medicine plays an important role in the treatment of diabetic foot with infection, sepsis, septic shock, arteriosclerosis obliterans, and thromboangitis obliterans.

OBJECTIVE: To compare the difference in forefoot width between minimally invasive extra-articular osteotomy via small incision and traditional Chevron osteotomy in the treatment of hallux valgus. METHODS: A retrospective analysis was conducted on the clinical data of 45 patients with hallux valgus between April 2019 and July 2022. Among them, 22 cases underwent minimally invasive extra-articular osteotomy via small incision (minimally invasive group), and 23 cases underwent traditional Chevron osteotomy (traditional group). There was no significant difference in the baseline data between the two groups ( P>0.05), including gender, age, affected side, Mann classification of hallux valgus, disease duration, and preoperative intermetatarsal angle (IMA), hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), bony forefoot width, soft tissue forefoot width, osteophyte width, and American Orthopaedic Foot and Ankle Society (AOFAS) score. The osteotomy healing time and the occurrence of complications in the two groups were recorded. The differences between pre- and post-operation (changes) in various imaging indicators and AOFAS scores in the two groups were calculated. And the bony forefoot width and soft tissue forefoot width at 1, 6, and 12 months after operation were also recorded and compared between the two groups. RESULTS: One case of skin injury occurred during operation in the minimally invasive group, while 3 cases of poor wound healing occurred after operation in the traditional group. None of the patients experienced infections, nerve injuries, or other complications. All patients were followed up 12-31 months (mean, 22.5 months). The osteotomy healed in the two groups and no significant difference in healing time between the two groups was found ( P>0.05). The IMA, HVA, DMAA, osteophyte width, and AOFAS score at 12 months after operation significantly improved compared to those before operation ( P<0.05). There was no significant difference between the two groups in the changes of IMA, HVA, and osteophyte width ( P>0.05). However, the differences in the changes of AOFAS score and DMAA were significant ( P<0.05). There was no significant difference between the two groups in bony and soft tissue forefoot widths at different time points after operation ( P>0.05). However, there were significant differences in the two groups between the pre- and post-operation ( P<0.05). CONCLUSION The minimally invasive extra-articular osteotomy via small incision for hallux valgus, despite not removing the medial osteophyte of the first metatarsal, can still effectively improve the forefoot width and osteophyte width. While correcting the IMA and HVA, it can more effectively restore the DMAA, resulting in better AOFAS scores.

OBJECTIVE: To investigate the correlation between the anterior talofibular ligament (ATFL) injury and the pathological changes of the anterior tibiotalar fat pad (ATFP) based on MRI. METHODS: The clinical and imaging data of 217 patients with ankle sprain who met the selection criteria between January 2019 and March 2024 were retrospectively analyzed. There were 113 males and 104 females with an average age of 38.2 years ranging from 18 to 60 years. Patients were divided into mild group ( n=106), moderate group ( n=63), and severe group ( n=48) according to the degree of ATFL injury. There was no significant difference in gender, side, and body mass index among the 3 groups ( P>0.05). The age of the mild group was significantly older than that of the moderate and severe groups ( P<0.05). The imaging parameters including the longest and shortest sagittal axis, the largest thickness, the longest and shortest transverse axis, the ATFP area, the area of ATFP high-signal region, and the anterior distal tibial angle (ADTA) were measured according to the MRI and X-ray films of patients. According to the morphology of ATFP, the patients were divided into type Ⅰ ( n=128), type Ⅱ ( n=73), and type Ⅲ ( n=16) based on the severity of the lesions. The distribution of ATFP types, ATFP area, area of ATFP high-signal region, and the ratio of area of ATFP high-signal region to ATFP area at the same level were statistically analyzed and compared among different ATFL injury groups. Additionally, radiographic parameters were compared across different ATFP types. Spearman rank correlation analysis was used to assess the relationships between ATFP area, area of ATFP high-signal region, and the ratio of area of ATFP high-signal region to ATFP area at the same level with patient baseline data. Through analysis of the area under curve (AUC) of ROC, optimal variables were selected for quantification to predict ATFL injury. RESULTS: There were significant differences in ATFP types among different ATFL injury groups ( P<0.05). The mild group had a higher proportion of type Ⅰ, the moderate group had a higher proportion of type Ⅱ, and the severe group had higher proportions of both typeⅡ and type Ⅲ. No significant difference was found in ATFP area among the different ATFL injury groups ( P>0.05). However, the area of ATFP high-signal region and the ratio of area of ATFP high-signal region to ATFP area at the same level were significantly lower in the mild group compared to the moderate and severe groups ( P<0.05). Except for the longest sagittal axis, maximum thickness, and longest transverse axis, which were significantly smaller in ATFP types Ⅱ and Ⅲ compared to type Ⅰ ( P<0.05), there was no significant difference in the remaining radiographic parameters among the different ATFP types ( P>0.05). Spearman rank correlation analysis revealed that ATFP area was negatively correlated with patient gender ( P<0.05), while area of ATFP high-signal region and the ratio of area of ATFP high-signal region to ATFP area at the same level were negatively correlated with patient age ( P<0.05). Through analysis of the AUC for the response variable ATFP injury, the combined diagnostic AUC of ROC for the reciprocal of the maximum thickness and the reciprocal of the area of ATFP high-signal region was 0.839 (asymptotic P<0.001). The corresponding cutoff value when the Youden index reached its maximum was 0.570 3. CONCLUSION As the severity of ATFL injury increases, the ATFP undergoes gradual morphological and functional changes. Classification based on ATFP types can assist in assessing the level of ATFL injury, thereby aiding in the prevention of post-traumatic osteoarthritis.

OBJECTIVE: To investigate the efficacy of minimally invasive osteotomy with preservation of blood supply to the transversely transported bone segment in the treatment of chronic ischemic lower limb diseases using tibial transverse bone transport. METHODS: A retrospective analysis was conducted on the clinical data of 12 patients with chronic ischemic lower limb diseases who met the selection criteria and were treated between June 2016 and December 2023. The cohort included 7 males and 5 females, aged 26-87 years (mean, 61.2 years). Among them, 7 patients had diabetic foot (DF), including 2 cases complicated by arteriosclerosis obliterans (ASO), with a DF duration ranging from 1.7 to 23.0 months (mean, 9.6 months) and ulcer sizes ranging from 3.2 cm×2.4 cm to 10.0 cm×6.6 cm. Three patients had ASO with a disease duration of 1.7-23.0 months (mean, 10.4 months) and ulcer or post-amputation wound sizes ranging from 2.2 cm×2.1 cm to 12.0 cm×7.7 cm. Additionally, 2 patients with thromboangiitis obliterans (TAO) had a disease duration of 7 and 12 months, respectively. Preoperatively, the mean foot skin temperature was (27.63±0.34)℃, and the visual analogue scale (VAS) score was 8.5±0.7. All patients underwent tibial transverse bone transport using minimally invasive osteotomy while preserving the blood supply to the transported bone segment. Postoperative complications and foot ulcer healing were observed. The effectiveness of tibial transverse bone transport was evaluated by comparing preoperative and postoperative foot skin temperature, VAS scores, as well as through CT angiography (CTA). RESULTS: One DF patient with ASO was lost to follow-up, while the remaining 11 patients were followed up 10-29 months (mean, 20.5 months). One DF patient had a displaced fracture at the site of tibial transport due to trauma, which healed after plaster immobilization; 1 DF patient had a small amount of pigmentation in the skin of the donor site, but the blood circulation was good; no complication such as pin tract infection, skin necrosis, or osteomyelitis occurred in the donor site of all patients. At 2-3 weeks postoperatively, the foot skin temperature was (34.21±0.65)℃, and the VAS score was 0.3±0.1, both significantly improved compared to preoperative ones ( t=-31.578, P<0.001; t=49.000, P<0.001). Two TAO patients experienced recurrent, persistent, intolerable pain at 7-10 days postoperatively, with no reduction in ulcer size or necrotic areas; 1 underwent toe amputation, and the other required a mid-leg amputation. The remaining patients achieved complete ulcer healing, with healing time ranging from 5.1 to 9.2 weeks (mean, 6.8 weeks). CTA showed no new vascular occlusions or embolisms. X-ray films at 4 months postoperatively demonstrated proper repositioning and good healing of the transported tibial bone segment. CONCLUSION The application of minimally invasive osteotomy with preserved blood supply to the transversely transported bone segment in tibial transverse bone transport for the treatment of chronic ischemic lower limb diseases effectively minimizes extensive soft tissue dissection, reduces surgical soft tissue damage, and better maintains local blood supply. This approach lowers the risk of postoperative infection and skin necrosis while accelerating postoperative recovery.
