BACKGROUND: Considering the ability of the health and self-management in diabetes questionnaire (HASMID-10) to verify the impact of self-management on diabetes, we highlight its relevance to scientific research and clinical applicability. However, to date, no study has been conducted to scientifically support its use in other languages. OBJECTIVE: To translate, cross-culturally adapt, and validate the HASMID-10 into the Brazilian Portuguese. DESIGN AND SETTING: A translation, cross-cultural adaptation, and validation study conducted at Ceuma University. METHODS: Study was conducted in accordance with the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments. We included participants of both sexes diagnosed with diabetes, aged between 18 and 64 years, and without cognitive deficits or any other limitations that would prevent them from answering the questionnaire. We assessed participants using the problem areas in diabetes (PAID) scale and HASMID-10. We assessed reliability using a test-retest model with a 7-day interval between assessments. We used intraclass correlation coefficient (ICC), 95% confidence interval (CI), standard error of measurement (SEM), minimum detectable difference (MDD), Spearman correlation coefficient, and floor and ceiling effects. RESULTS: Sample comprised 116 participants, most of whom were women, overweight, non-practitioners of physical activity, and nonsmokers. We observed significant correlations (P = 0.006; rho = -0.256) between the HASMID-10 and PAID, adequate reliability (ICC = 0.780) and internal consistency (Cronbach's alpha = 0.796). No ceiling or floor effects were observed. CONCLUSION: HASMID-10 has adequate measurement properties and may be used for Brazilians.

ETHNOPHARMACOLOGICAL RELEVANCE: Diabetic nephropathy (DN) was a major cause of end-stage renal failure and a common microvascular complication in patients with diabetes mellitus (DM). Acteoside (ACT) was the main ingredient extracted from the leaves of Rehmannia glutinosa, which had the functions of entering the lung, moisturizing the skin and relieving itching, nourishing yin and tonifying the kidney, cooling blood, and stopping bleeding. ACT had attracted worldwide interest because of its therapeutic effects on DM and its complications. AIM OF THE STUDY: To clarify the metabolic profiles and targets of ACT in db/db mice based on metabolomics and network pharmacology studies. MATERIALS AND METHODS: Db/db mice were used to observe the biochemical indices and histopathological changes in the kidney to evaluate the pharmacological effects of ACT on DN. Untargeted metabolomics studies were performed to investigate by UHPLC-LTQ-Orbitrap MS on urine, serum, and kidney samples. The key targets and pathways were analyzed by network pharmacology. For the pathways enriched by untargeted metabolomics, targeted metabolomics by UHPLC-QQQ-MS/MS was performed in kidney samples for validation. Sensitive biomarkers in kidney samples were evaluated. The effect of ACT on the improvement of DN from the perspective of metabolism of small molecules in vivo was described. RESULTS: ACT could delay the progression of DN and improve the degree of histopathological damage to the kidney. The pathways were focused on amino acid metabolism by untargeted metabolomics. Through network pharmacology analysis, the effect pathways were related to signal transduction, carbohydrate, lipid, amino acid metabolism and mainly affected the endocrine and immune systems. Amino acid metabolism was disturbed in the kidney of db/db mice, which could be callback by ACT, such as tryptophan, glutamine, cysteine, leucine, threonine, proline, phenylalanine, histidine, serine, arginine, asparagine by targeted metabolomics. CONCLUSIONS: In conclusion, this study provided strong support for ACT on DN treatment in clinics. Meanwhile, the Rehmannia glutinosa was used fully to raise the income level of farmers economically, while achieving the social benefit of empowering rural revitalization.

Abstract The main purpose of this study was to find out a possible association between ABO blood groups or Rh and diabetes mellitus (DM) in the local population of eight (8) different towns of Karachi, Pakistan. For this purpose a survey was carried out in Karachi to have a practical observation of these towns during the period of 9 months from June 2019 to Feb. 2020. Out of eighteen (18) towns of Karachi, samples (N= 584) were collected from only eight (8) Towns of Karachi and gave a code-number to each town. Diabetic group sample was (n1=432) & pre-diabetes sample was (n2 =152). A standard Abbot Company Glucometer for Random Blood Sugar (RBS) and Fasting Blood Sugar (FBS) tests, standard blood anti sera were used for ABO/Rh blood type. Health assessment techniques were performed ethically by taking informed consent from all registered subjects. Finally data was analyzed by SPSS version 20.0. In our current study, the comparison of ABO blood groups frequencies between diabetic and pre-diabetic individuals were carried out. The percentage values of blood Group-B as given as: (32% in DM vs. 31% in pre-diabetics), followed by blood Group-O as: (18% in DM vs. 11% in pre-diabetics). Contrary to Group-"B" & "O", blood Group-A and Group-AB were distribution percentage higher pre-diabetic as compared to DM patients, as given as: Group-A (32% in pre-diabetics vs. 26% in DM) & Group-AB (26% in pre-diabetics vs. 24% in diabetic's patients). In addition, percentage distribution of Rh system was also calculated, in which Rh+ve Group was high and more common in DM patients as compared to pre-diabetics; numerically given as: Rh+ve Group (80% in DM vs. 72% in pre-diabetics). Different views and dimensions of the research topic were studied through literature support, some have found no any association and some established a positive association still some were not clear in making a solid conclusion. It is concluded that DM has a positive correlation with ABO blood groups, and people with Group-B have increased susceptibility to DM disease.

Resumo O objetivo principal deste estudo foi descobrir uma possível associação entre grupos sanguíneos ABO ou Rh e diabetes mellitus (DM) na população local de oito (8) diferentes cidades de Karachi, Paquistão. Para tanto, foi realizado um levantamento em Karachi para observação prática dessas cidades durante o período de 9 meses de junho de 2019 a fevereiro de 2020.De dezoito (18) cidades de Karachi, as amostras (N = 584) foram coletadas de apenas oito (8) cidades de Karachi e deram um número-código para cada cidade. A amostra do grupo de diabéticos foi (n1 = 432) e a amostra de pré-diabetes foi (n2 = 152). Um glicômetro padrão da Abbot Company para testes de açúcar no sangue aleatório (RBS) e açúcar no sangue em jejum (FBS), antissoros de sangue padrão foram usados ​​para o tipo de sangue ABO / Rh. As técnicas de avaliação de saúde foram realizadas de forma ética, tomando o consentimento informado de todos os indivíduos registrados. Finalmente, os dados foram analisados ​​pelo SPSS versão 20.0.No presente estudo, foi realizada a comparação das frequências dos grupos sanguíneos ABO entre diabéticos e pré-diabéticos. Os valores percentuais do sangue do Grupo-B são dados como: (32% em DM vs. 31% em pré-diabéticos), seguido pelo sangue do Grupo-O como: (18% em DM vs. 11% em pré-diabéticos). Ao contrário dos Grupos "B" e "O", sangue do Grupo-A e Grupo-AB tiveram distribuição percentual maior de pré-diabéticos em comparação com pacientes com DM, dado como: Grupo-A (32% em pré-diabéticos vs. 26% em DM) e Grupo AB (26% em pré-diabéticos vs. 24% em pacientes diabéticos). Além disso, também foi calculada a distribuição percentual do sistema Rh, no qual o Grupo Rh + ve foi elevado e mais comum em pacientes com DM em comparação aos pré-diabéticos; dados numericamente como: Grupo Rh + ve (80% em DM vs. 72% em pré-diabéticos). Diferentes visões e dimensões do tema de pesquisa foram estudadas com o suporte da literatura, alguns não encontraram nenhuma associação e alguns estabeleceram uma associação positiva, embora alguns não estivessem claros em fazer uma conclusão sólida. Conclui-se que o DM tem correlação positiva com os grupos sanguíneos ABO, e as pessoas com o Grupo B têm maior suscetibilidade à doença DM.

Due to the severe side effects revealed by most of the currently used antidiabetic medicines, search for finding new and safe drugs to manage diabetes is continued. Naphthoquinones possessing strong antioxidant properties have been employed as candidates for diabetes therapy. Present study is aimed at finding the antioxidant and hypoglycaemic potential of some novel derivatives of 2-phenylamino-1,4-naphthoquinones (PAN) including chloro, nitro, methyl and bromo (5a-d) derivatives synthesized by single pot experiment. Product crystals were purified by TLC and characterized by FT-IR. The antioxidant potential of the compounds was assayed through DPPH radical scavenging and reducing power activities noted as UV-vis. absorbance. The DPPH assay has showed the powerful antioxidant activity of nitro and bromo derivatives, while the nitro derivative showed the significant reduction potential towards FRAP assay. Hypoglycaemic potential of the compounds was studied in rat animal model. All synthesized compounds revealed better hypoglycaemic activity; however, the chloro-derivative exhibited the more potent hypoglycaemic activity showing about 43% reduction in the mean blood glucose levels of the treated animals. As the bioreduction of naphthoquinones may be influenced by changing its redox properties, it has been noticed that the e-donating resonance effect (+R) of 'chloro' group has shown the significant effects on biological activity through stabalization of its imine form which limits the potential of generation of free radicals during bioreduction of quinones and thus has been proposed as the reason of its hypoglycaemic activity. Future studies employing the properties of e-donating groups of PAN may optimize the drug-receptor interaction for better drug designing and drug development strategies against diabetes and also for the clinical trials.

Em razão dos graves efeitos colaterais causados pela maioria dos medicamentos antidiabéticos atualmente utilizados, continua a busca por novos medicamentos seguros para o controle do diabetes. As naftoquinonas, que possuem fortes propriedades antioxidantes, têm sido empregadas como candidatas à terapia do diabetes. O presente estudo visa encontrar o potencial antioxidante e hipoglicemiante de alguns novos derivados de 2-fenilamino-1,4-naftoquinonas (PAN), incluindo derivados de cloro, nitro, metil e bromo (5a-d) sintetizados por experimento em pote único. Os cristais do produto foram purificados por TLC e caracterizados por FT-IR. O potencial antioxidante dos compostos foi testado por meio de atividades de sequestro de radicais DPPH e redução de energia observada como absorção no UV-vis. O ensaio DPPH mostrou a poderosa atividade antioxidante dos derivados nitro e bromo, enquanto o derivado nitro mostrou o potencial de redução significativo para o ensaio FRAP. O potencial hipoglicêmico dos compostos foi estudado em modelo animal de rato. Todos os compostos sintetizados revelaram melhor atividade hipoglicemiante; no entanto, o derivado cloro apresentou atividade hipoglicêmica mais potente, com redução de 43% nos níveis médios de glicose no sangue dos animais tratados. Como a biorredução de naftoquinonas pode ser influenciada pela alteração de suas propriedades redox, notou-se que o efeito da doação eletrônica por ressonância (+R) do grupo "cloro" tem sido significativo na atividade biológica por meio da estabilização de sua forma imina, que limita o potencial de geração de radicais livres durante a biorredução de quinonas, e, portanto, tem sido proposto como a razão de sua atividade hipoglicemiante. Estudos futuros empregando as propriedades de grupos de doação eletrônica de PAN podem otimizar a interação droga-receptor para melhor planejamento de medicamentos e estratégias de desenvolvimento de medicamentos contra o diabetes e também para os ensaios clínicos.

Objetivo: analizar los efectos de las tecnologías educativas en la prevención y tratamiento de la úlcera diabética. Método: revisión sistemática realizada en siete bases de datos, un índice bibliográfico, una biblioteca electrónica y literatura gris. La muestra estuvo compuesta por 11 ensayos clínicos controlados aleatorizados. La síntesis de los resultados fue descriptiva y mediante metaanálisis. Resultados: las tecnologías educativas predominantes fueron la capacitación y la orientación verbal, se destacaron las tecnologías blandas-duras. En comparación con la atención habitual, las tecnologías educativas demostraron ser un factor protector para prevenir la incidencia de úlcera diabética (RR=0,40; IC 95%=0,18-0,90; p=0,03) y la evaluación de certeza de evidencia fue baja. Las tecnologías educativas también demostraron ser un factor protector para prevenir la incidencia de amputación en miembros inferiores (RR=0,53; IC 95%=0,31-0,90; p=0,02) y la certeza de evidencia fue muy baja. Conclusión: tecnologías educativas blandas-duras, como orientación verbal estructurada, juegos educativos, clase expositiva, capacitación teórico-práctica, video educativo, folder, rotafolio educativo y dibujos lúdicos, y tecnologías duras, como calzado terapéutico, plantillas, termómetro infrarrojo digital, kits para el cuidado de los pies, aplicación de telemedicina y teléfono móvil, resultaron efectivas para la prevención y el tratamiento de la úlcera diabética, sin embargo, es necesario que se realicen estudios más robustos.

Objective: to analyze the effects of educational technologies in the prevention and treatment of diabetic ulcers. Method: a systematic review conducted in seven databases, a bibliographic index, an electronic library and the Gray Literature. The sample consisted of 11 randomized controlled clinical trials. The synthesis of the results was descriptive and through meta-analysis. Results: the predominant educational technologies were training sessions and verbal guidelines, with soft-hard technologies standing out. When compared to usual care, the educational technologies presented a protective factor to prevent the incidence of diabetic ulcers (RR=0.40; 95% CI=0.18-0.90; p=0.03) and the certainty of the evidence assessment was low. The educational technologies also had a protective factor to prevent the incidence of lower limb amputations (RR=0.53; 95% CI=0.31-0.90; p=0.02) and certainty of the evidence was very low. Conclusion: soft-hard educational technologies such as structured verbal guidelines, educational games, lectures, theoretical-practical training sessions, educational videos, folders, serial albums and playful drawings, and hard technologies such as therapeutic footwear, insoles, infrared digital thermometer, foot care kits, Telemedicine app and mobile phone use, were effective for the prevention and treatment of diabetic ulcers, although more robust studies are required.

Purpose: To identify risk factors and evaluate outcomes of patients with delayed presentation and advanced diabetic retinopathy in our safety-net county hospital population. Methods: A retrospective study was performed on 562 patients who presented with a new diagnosis of diabetic retinopathy (DR). Delayed presentation was defined as moderate or severe nonproliferative diabetic retinopathy (NPDR) or proliferative diabetic retinopathy (PDR) at the initial visit. Comparisons between patient groups were performed with chi-square or Fisher's exact test for categorical variables and multinomial logistic regression for multivariable analysis. Linear and logistic regression modeling with general estimating equations to account for patients having two eyes was used to compare eye-level outcomes. Results: Lack of a primary care provider (PCP) was highest in patients who presented initially with PDR (28.8%), compared to 14.3% in moderate/severe NPDR, 12.4% in mild NPDR, and 7.6% in no DR groups (P < 0.001). Only 69.4% of patients with a PCP had an ophthalmology screening referral. Highest lack of referral (47.2%) was seen in the PDR group (P = 0.002). Patients with PDR were more likely to be uninsured (19.2%) compared to no and mild DR groups, with rates of 7.6% and 9.0%, respectively (P = 0.001). The PDR group had worse initial and final visual acuities (P < 0.001). Conclusions: Several risk factors were noted for delayed DR presentation, including lack of PCP, lack of screening referral, and uninsured/underinsured status. Patients with advanced DR at presentation had worse final visual outcomes despite aggressive treatment. Translational Relevance: Screening programs targeting populations with identified risk factors are essential for improving outcomes.

OBJECTIVE: To examine the protective effect of ginsenoside Rb1 (Rb1), the main component of Renshen (), on cardiomyopathy in db/db mice exposed to chronic intermittent hypoxia (CIH) and explore the potential underlying mechanism of Rb1 in treating diabetic cardiomyopathy (DCM). METHODS: The db/db mice were randomly separated into five groups: normal control group, model group, Rb1 20 mg/kg group, Rb1 40 mg/kg group, and glucagon-like peptide-1 (GLP-1) group. Mice were exposed to air-condition or CIH for 8 weeks, and Rb1 and GLP-1 were administrated before CIH exposure every day. Oral glucose tolerance test (OGTT), intraperitoneal insulin tolerance test (IPITT), total cholesterol (TC), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) were detected to evaluate glycolipid metabolism. The level of insulin was detected by a mouse enzyme-linked immunosorbent assay (ELISA). Cardiac function was detected by echocardiography, and myocardial pathology was observed by hematoxylin-eosin and Masson staining. The expression of collagen Ⅰ and collagen Ⅲ was detected by immunohistochemistry. Adenosine monophosphate-activated protein kinase (AMPK)/Nrf2/heme oxygenase-1 (HO-1) signaling pathway was detected by Western blot and immunofluorescence. RESULTS: Rb1 treatment could improve glucose tolerance and the level of cardiac function indexes, and inhibit the level of oxidative stress indexes and the expression of collagen Ⅰ and collagen Ⅲ. Moreover, Rb1 treatment enhanced AMPK phosphorylation and increased Nrf2 and HO-1 expression. CONCLUSION: Rb1 treatment alleviated CIH-induced diabetic cardiomyopathy and glycolipid metabolism disorders in db/db mice by inhibiting oxidative stress and regulating the AMPK/Nrf2/HO-1 signaling pathway.

Background: Many evidence-based health interventions, particularly in low-income settings, have failed to deliver the expected impact. We designed an Adaptive Diseases Control Expert Programme in Tanzania (ADEPT) to address systemic challenges in health care delivery and examined the feasibility, acceptability and effectiveness of the model using tuberculosis (TB) and diabetes mellitus (DM) as a prototype. Methods: This was an effectiveness-implementation hybrid type-3 design that was implemented in Dar es Salaam, Iringa and Kilimanjaro regions. The strategy included a stepwise training approach with web-based platforms adapting the Gibbs' reflective cycle. Health facilities with TB services were supplemented with DM diagnostics, including glycated haemoglobin A1c (HbA1c). The clinical audit was deployed as a measure of fidelity. Retrospective and cross-sectional designs were used to assess the fidelity, acceptability and feasibility of the model. Results: From 2019-2021, the clinical audit showed that ADEPT intervention health facilities more often identified median 8 (IQR 6-19) individuals with dual TB and DM, compared with control health facilities, median of 1 (IQR 0-3) (p = 0.02). Likewise, the clinical utility of HbA1c on intervention sites was 63% (IQR:35-75%) in TB/DM individuals compared to none in the control sites at all levels, whereas other components of the standard of clinical management of patients with dual TB and DM did not significantly differ. The health facilities showed no difference in screening for additional comorbidities such as hypertension and malnutrition. The stepwise training enrolled a total of 46 nurse officers and medical doctors/specialists for web-based training and 40 (87%) attended the workshop. Thirty-one (67%), 18 nurse officers and 13 medical doctors/specialists, implemented the second step of training others and yielded a total of 519 additional front-line health care workers trained: 371 nurses and 148 clinicians. Overall, the ADEPT model was scored as feasible by metrics applied to both front-line health care providers and health facilities. Conclusions: It was feasible to use a stepwise training and clinical audit to support the integration of TB and DM management and it was largely acceptable and effective in differing regions within Tanzania. When adapted in the Tanzania health system context, the model will likely improve quality of services.

Introduction: Diabetes and thyroid dysfunction often co-exist. One autoimmune disorder always invites another and it has been reported that such co-morbid ailments always become detrimental to the health of the patients. Materials and methods: In our previous work, we elucidated the interactions of diabetes and hypothyroidism on testicular development and spermatogenesis. However, the present study illuminates the interface between diabetes and hyperthyroidism, where 16 ICR pregnant primiparous mice were used and subsequently 48 male pups were randomly selected (n=12/group) and separated into 4 groups: control (C), diabetic (D), diabetic + hyperthyroidism (DH) and hyperthyroidism (H). Results: Computerized sperm analyses showed significant reductions in count by 20% and increases of 15% in D and H animals, respectively, vs. controls. However, rapid progressive sperm motility was significantly lower only in D (30%) compared with C mice. Our histomorphometric investigation depicted damaging effects on testicular and epididymal tissues; the stroma adjacent to the seminiferous tubules of the D mice revealed edematous fluid and unstructured material. However, in the epididymis, germ cell diminution contraction of tubules, compacted principal and clear cells, lipid vacuolization, atypical cellular connections, exfoliated epithelial cells, and round spermatids were conspicuous in DH mice. Discussion: Collectively, our experiment was undertaken to ultimately better recognize male reproductive disorders in diabetic-hyperthyroid patients.

Introduction: Vascular complications and neuropathy may develop in the presence of metabolic syndrome. The aim of our study was to measure the cardiovascular autonomic function following physical training in patients with metabolic syndrome with and without diabetes. Subjects and methods: 56 patients with metabolic syndrome (32 men/24 women, 40 non-diabetic patients (NDMetS)/16 diabetic patients (DMetS) [mean ± SD]: age: 50.35 ± 8.03 vs. 56.8 ± 9.30 years, p=0.023; baseline BMI: 32.2 ± 7.03 vs. 32.8 ± 5.94 kg/m2, p=0.739) were involved in our study. All tests and measurements were carried out before and following a 3-month physical training period. Autonomic function was assessed by means of five standard cardiovascular reflex tests. ECG repolarization parameters, including short-term QT variability and stress-ECG were also measured. Results: In the whole population, Valsalva-ratio (VR) and the autonomic score (AS) improved following training (VR: 1.49 ± 0.24 vs. 1.64 ± 0.34, p=0.001; AS: 2.05 ± 1.73 vs. 1.41 ± 1.36, p=0.015) accompanied by the significant decrease of the systolic (150.3 ± 16.12 vs. 134.1 ± 16.67 mmHg, p<0.001) and diastolic (90.64 ± 12.8 vs. 82.79 ± 11.1 mmHg, p<0.001) blood pressure. An improvement in VR was detected in NDMetS patients following training (1.51 ± 0.24 vs. 1.67 ± 0.31, p= 0.002). No significant changes could be detected in autonomic tests' results in the DMetS patient group following training. The applied exercise training program did not lead to significant changes in ECG repolarization. The stress-ECG test in the whole study population yielded a significant increase in the test duration (12.9 ± 3.76 vs. 15.1 ± 2.96 min, p<0.001) and in the test load (10.5 ± 2.78 vs. 11.6 ± 2.39 MET, p<0.001). The load capability improved significantly in both subgroups: 11.1 ± 2.04 vs. 12.1 ± 1.82, (p<0.001) and 9.0 ± 3.64 vs. 10.4 ± 3.05, (p=0.033) in subpopulations of NDMetS and DMetS, respectively. The DMetS patients achieved a significantly lower MET score at baseline (p=0.039) and following training (p=0.044) in comparison to the NDMetS patients. Conclusion: The three-month exercise program improved the Valsalva-ratio and the AN score in the MetS patients, that is potentially protective against cardiovascular events. The training had some beneficial effect on blood pressure and the results of the stress-ECG tests in both groups. The absence of significant change in the reflex tests in DMetS group reflects an impaired adaptation compared to the NDMestS group.

Diabetic foot ulcer (DFU) is a major complication of diabetes and is associated with a high risk of lower limb amputation and mortality. During their lifetime, 19%-34% of patients with diabetes can develop DFU. It is estimated that 61% of DFU become infected and 15% of those with DFU require amputation. Furthermore, developing a DFU increases the risk of mortality by 50%-68% at 5 years, higher than some cancers. Current standard management of DFU includes surgical debridement, the use of topical dressings and wound decompression, vascular assessment, and glycemic control. Among these methods, local treatment with dressings builds a protective physical barrier, maintains a moist environment, and drains the exudate from DFU wounds. This review summarizes the development, pathophysiology, and healing mechanisms of DFU. The latest research progress and the main application of dressings in laboratory and clinical stage are also summarized. The dressings discussed in this review include traditional dressings (gauze, oil yarn, traditional Chinese medicine, and others), basic dressings (hydrogel, hydrocolloid, sponge, foam, film agents, and others), bacteriostatic dressings, composite dressings (collagen, nanomaterials, chitosan dressings, and others), bioactive dressings (scaffold dressings with stem cells, decellularized wound matrix, autologous platelet enrichment plasma, and others), and dressings that use modern technology (3D bioprinting, photothermal effects, bioelectric dressings, microneedle dressings, smart bandages, orthopedic prosthetics and regenerative medicine). The dressing management challenges and limitations are also summarized. The purpose of this review is to help readers understand the pathogenesis and healing mechanism of DFU, help physicians select dressings correctly, provide an updated overview of the potential of biomaterials and devices and their application in DFU management, and provide ideas for further exploration and development of dressings. Proper use of dressings can promote DFU healing, reduce the cost of treating DFU, and reduce patient pain.

Diabetes mellitus is a main risk factor for periodontitis, but until now, the underlying molecular mechanisms remain unclear. Diabetes can increase the pathogenicity of the periodontal microbiota and the inflammatory/host immune response of the periodontium. Hyperglycemia induces reactive oxygen species (ROS) production and enhances oxidative stress (OS), exacerbating periodontal tissue destruction. Furthermore, the alveolar bone resorption damage and the epigenetic changes in periodontal tissue induced by diabetes may also contribute to periodontitis. We will review the latest clinical data on the evidence of diabetes promoting the susceptibility of periodontitis from epidemiological, molecular mechanistic, and potential therapeutic targets and discuss the possible molecular mechanistic targets, focusing in particular on novel data on inflammatory/host immune response and OS. Understanding the intertwined pathogenesis of diabetes mellitus and periodontitis can explain the cross-interference between endocrine metabolic and inflammatory diseases better, provide a theoretical basis for new systemic holistic treatment, and promote interprofessional collaboration between endocrine physicians and dentists.

Background and Purpose: Nonproliferative diabetic retinopathy (NPDR) occurs in the early stages of Diabetic retinopathy (DR), and the study of its metabolic markers will help to prevent DR. Hence, we aimed to establish a risk score based on multiple metabolites through untargeted metabolomic analysis of venous blood from NPDR patients and diabetic non-DR patients. Experimental Approach: Untargeted metabolomics of venous blood samples from patients with NPDR, diabetes melitus without DR were performed using high-performance liquid chromatography-mass spectrometry. Results: Detailed metabolomic evaluation showed distinct clusters of metabolites in plasma samples from patients with NPDR and diabetic non-DR patients. NPDR patients had significantly higher levels of phenylacetylglycine, L-aspartic acid, tiglylglycine, and 3-sulfinato-L-alaninate, and lower level of indolelactic acid, threonic acid, L-arginine (Arg), and 4-dodecylbenzenesulfonic acid compared to control. The expression profiles of these eight NPDR risk-related characteristic metabolites were analyzed using Cox regression to establish a risk score model. Subsequently, univariate and multivariate Cox regression analyses were used to determine that this risk score model was a predictor of independent prognosis for NPDR. Conclusions: Untargeted metabolome analysis of blood metabolites revealed unreported metabolic alterations in NPDR patients compared with those in diabetic non-DR patients or MH. In the venous blood, we identified depleted metabolites thA and Arg, indicating that they might play a role in NPDR development.

Sarcopenia and malnutrition have been associated in the elderly population with a poor prognosis in wound healing and with other adverse events, such as institutionalization or functional impairment. However, it is not known how these factors influence the prognosis of diabetic foot in the elderly. To answer this question, a prospective observational study of 45 patients over 65 years of age admitted with diagnoses of diabetic foot in a tertiary hospital has been conducted. All patients were assessed at admission and at 3 months after returning home to determine quality of life, pain, mobility and healing, overall hospital stay in relation to the presence of malnutrition (measured by BMI, CIPA scale and analytical parameters at admission of serum proteins and albumin), and sarcopenia measured by grip force, among other geriatric syndromes. The results found a relationship between altered sarcopenia and more pain and poorer quality of life, and altered BMI was related to a lower cure rate and worse mobility at follow-up. This study seems to indicate that, in the elderly population with diabetic foot, malnutrition and sarcopenia should be managed at the same time as the treatment of the diabetic foot itself.

Diabetic retinopathy (DR) is one of the main causes of blindness in people around the world. Early diagnosis and treatment of DR can be accomplished by organizing large regular screening programs. Still, it is difficult to spot diabetic retinopathy timely because the situation might not indicate signs in the primary stages of the disease. Due to a drastic increase in diabetic patients, there is an urgent need for efficient diabetic retinopathy detecting systems. Auto-encoders, sparse coding, and limited Boltzmann machines were used as a few past deep learning (DL) techniques and features for the classification of DR. Convolutional Neural Networks (CNN) have been identified as a promising solution for detecting and classifying DR. We employ the deep learning capabilities of efficient net batch normalization (BNs) pre-trained models to automatically acquire discriminative features from fundus images. However, we successfully achieved F1 scores above 80% on all efficient net BNs in the EYE-PACS dataset (calculated F1 score for DeepDRiD another dataset) and the results are better than previous studies. In this paper, we improved the accuracy and F1 score of the efficient net BNs pre-trained models on the EYE-PACS dataset by applying a Gaussian Smooth filter and data augmentation transforms. Using our proposed technique, we have achieved F1 scores of 84% and 87% for EYE-PACS and DeepDRiD.

Background: Diabetes disproportionately affects minorities and those with low socioeconomic status (SES) in the United States, and differences in behavioral lifestyles are largely responsible for the unequal distribution of diabetes among different groups. Methods: With data of 9,969 participants collected in the 2007-2008 and 2009-2010 cycles of the US National Health and Nutrition Examination Survey (NHANES), this study examined several mediators and their mediating effects in the connection between SES and the risk of diabetes. The SES is assessed by the income-to-poverty ratio (IPR), education level, and employment status. For the mediation analysis, we used health-related behaviors as mediators (smoking, alcohol use, consumption of green vegetables and fruits, physical activity and sedentary time, health insurance, and healthcare). In this study, the structural equation model was utilized to evaluate the mediating effects of behavioral lifestyle as a mediator in the relationship between SES and diabetes. Results: A total of 9,969 participants were included in this study. We found a negative nonlinear association between IPR and diabetes risk (Poverall < 0.001; Pnon-linear = 0.46), which was independent of the majority of known or suspected risk factors and confounding variables (gender, age, race). Participants with lower SES had higher risk of diabetes compared with those with higher SES. In mediating analysis, we found alcohol intake (OR = 0.996), physical activity (OR = 0.993), health insurance (OR = 0.998), and healthcare (OR = 1.002) mediated the IPR-diabetes association. But in the relationship between education status and diabetes, the mediation effect of alcohol intake (OR = 0.995), physical activity (OR = 0.991), and health care (OR = 1.008) were obvious. Likewise, alcohol intake (OR = 0.996), fruit intake (OR = 0.998), and health care (OR = 0.975) were important mediators in the association between employment status and diabetes. Conclusion: This study provides critical insights on the link between SES and diabetes. Our results highlight that poor health-related behaviors and limited access to healthcare are important pathways for increased diabetes risk related to those with low SES, particularly among Mexican Americans and males. They should be top priorities for agencies and healthcare providers to develop behavior-related interventions to reduce inequalities in diabetes risk.
