Mean platelet volume (MPV) as new marker of diabetic macrovascular complications in patients with different glucose homeostasis : Platelets in cardiovascular risk.

BACKGROUND: Platelets play an important role in the development of cardiovascular disease (CVD). Mean platelet volume (MPV) is considered as biological marker of platelets activity and function. The aim of the present study was to evaluate MPV values and its possible correlation with arterial stiffness and subclinical myocardial damage, in normal glucose tolerance patients (NGT), in newly diagnosed type 2 diabetic (T2DM) patients and in individuals with pre-diabetes. METHODS: We enrolled 400 newly diagnosed hypertensive patients. All patients underwent an Oral Glucose Tolerance test (OGTT). Arterial stiffness (AS) was evaluated with the measurement of carotid-femoral pulse wave velocity (PWV), augmentation pressure (AP) and augmentation index (AI). Echocardiographic recordings were performed using an E-95 Pro ultrasound system. RESULTS: Among groups there was an increase in fasting plasma glucose (FPG) (p < 0.0001), fasting plasma insulin (FPI) (p < 0.0001), high sensitivity c reactive protein (hs-CRP) levels (p < 0.0001) and a decrease in renal function as demonstrated by e-GFR values (p < 0.0001). From the NGT group to the T2DM group there was a rise in MPV value (p < 0.0001). Moreover, in the evaluation of arterial stiffness and subclinical myocardial damage, MPV showed a positive correlation with these parameters. CONCLUSIONS: In the present study we highlighted that MPV is significantly increased, not only in newly diagnosed T2DM patients, but also in early stage of diabetes, indicating that subjects with pre-diabetes present increased platelets reactivity. Moreover, our results suggest that MPV is associated with increased arterial stiffness and subclinical myocardial damage, indicating MPV as new marker of CV risk.

[Analysis of epidemiological characteristics and risk factors of catheter-associated urinary tract infections in patients with perineal and/or hip burns].

Objective: To explore the epidemiological characteristics and risk factors of catheter-associated urinary tract infections in patients with perineal and/or hip burns. Methods: This study was a retrospective case series study. From January 2018 to December 2022, 260 patients with perineal and/or hip burns and urinary catheters indwelling who met the inclusion criteria were admitted to the Department of Burns and Wound Repair of the Second Affiliated Hospital of Zhejiang University School of Medicine, including 192 males and 68 females, aged 20-93 years. The total incidence of catheter-associated urinary tract infections in patients with perineal and/or hip burns, the detection of pathogenic bacteria, and the resistance of major Gram-negative and Gram-positive bacteria to commonly used antimicrobial drugs in clinic were recorded. According to whether catheter-associated urinary tract infection occurred or not, the patients were divided into infection group (43 cases) and non-infection group (217 cases). The basic conditions including gender, age, total burn area, depth of perineal burn, depth of hip burn, and burn site on admission, complications of diabetes mellitus, inhalation injury, and hypoproteinaemia, invasive operations including tracheotomy and non-perineal/hip debridement/skin transplantation surgery, duration of catheter retention, number of urethral catheterization, and bladder irrigation of patients between the two groups were compared, and the independent risk factors influencing the occurrence of catheter-associated urinary tract infections in patients with perineal and/or hip burns were screened. Results: The total incidence of catheter-associated urinary tract infections in patients with perineal and/or hip burns in this study was 16.5% (43/260). The pathogens detected were predominantly Gram-negative, followed by fungi; the main Gram-negative bacterium was Klebsiella pneumoniae, and the main Gram-positive bacterium was Enterococcus faecalis. The resistance rates of Klebsiella pneumoniae to amoxicillin/clavulanic acid, amitraz, amikacin, ciprofloxacin, ceftriaxone, and levofloxacin were higher than 70.0%, the resistance rates of Klebsiella pneumoniae to cefoxitin, cefoperazone/sulbactam, cefepime, meropenem, imipenem, and piperacillin/tazobactam ranged from 56.3% to 68.8%, and the resistance rates of Klebsiella pneumoniae to ceftazidime and tigecycline were lower than 50.0%. The resistance rates of Enterococcus faecalis to ciprofloxacin and penicillin were both 85.7%, the resistance rates of Enterococcus faecalis to erythromycin, clindamycin, moxifloxacin, and tetracycline ranged from 14.3% to 57.1%, and the resistance rates of Enterococcus faecalis to linezolid, tigecycline, and vancomycin were all 0. The differences were statistically significant between the two groups in terms of gender, status of complication of hypoproteinaemia, depth of perineal burn, status of non-perineal/hip debridement/skin transplantation surgery, status of bladder irrigation, number of urethral catheterization, and duration of catheter retention of patients (with χ2 values of 7.80, 4.85, 10.68, 9.11, and 16.48, respectively, and Z values of -4.88 and -5.42, respectively, P<0.05). There were no statistically significant differences in the age, total burn area, complications of diabetes mellitus and inhalation injury, burn site, depth of hip burns, and status of tracheotomy of patients between the two groups (P>0.05). Multifactorial logistic regression analysis showed that gender, deep partial-thickness perineal burns, non-perineal/hip debridement/skin transplantation surgery, bladder irrigation, and duration of catheter retention were the independent risk factors for catheter-associated urinary tract infections in patients with perineal and/or hip burns (with odds ratios of 2.86, 2.63, 2.79, 2.34, and 1.04, respectively, with 95% confidence intervals of 1.21-6.73, 1.03-6.71, 1.03-7.59, 1.05-5.22, and 1.02-1.06, respectively, P<0.05). Conclusions: The incidence of catheter-associated urinary tract infections is high in patients with perineal and/or hip burns, with Klebsiella pneumoniae as the predominant pathogenic bacteria having a high resistance rate to commonly used antimicrobial drugs in clinic. Gender, deep partial-thickness perineal burns, non-perineal/hip debridement/skin transplantation surgery, bladder irrigation, and duration of catheter retention are the independent risk factors for catheter-associated urinary tract infections in patients with perineal and/or hip burns.

Duration-specific association between plasma IGFBP7 levels and diabetic complications in patients with type 2 diabetes mellitus.

OBJECTIVE: Insulin-like growth factor binding protein 7 (IGFBP7) has a strong affinity to insulin. This study aimed to evaluate the relationship between IGFBP7 and complications among type 2 diabetes mellitus (T2DM) patients. DESIGN: A total of 1449 T2DM patients were selected from a cross-sectional study for disease management registered in the National Basic Public Health Service in Changshu, China, and further tested for their plasma IGFBP7 levels. Logistic regressions and Spearman's rank correlation analyses were used to explore the associations of IGFBP7 with diabetic complications and clinical characteristics, respectively. RESULTS: Among the 1449 included T2DM patients, 403 (27.81%) had complications. In patients with shorter duration (less than five years), the base 10 logarithms of IGFBP7 concentration were associated with T2DM complications, with an adjusted odds ratio (OR) of 2.41 [95% confidence interval (95%CI) = 1.06-5.48]; while in patients with longer duration (more than five years), plasma IGFBP7 levels were not associated with T2DM complications. Furthermore, in T2DM patients with shorter duration, those with two or more types of complications were more likely to have higher levels of IGFBP7. CONCLUSION: IGFBP7 is positively associated with the risk of complication in T2DM patients with shorter duration.

A multi-state analysis of disease trajectories and mental health transitions in patients with type 2 diabetes: A population-based retrospective cohort study utilizing health administrative data.

AIMS: To investigate the risk of major depression and dementia in patients with type 2 diabetes, including dementia resulting from depression, and their impact on diabetes-related complications and mortality. METHODS: We conducted a population-based retrospective cohort study including 11,441 incident cases of diabetes in 2015-2017, with follow-up until 2022. A multi-state survival analysis was performed on a seven-state model with 15 transitions to capture disease progression and onset of mental disorders. RESULTS: Eight-year probabilities of depression, dementia, diabetes-related complications, and death were 9.7% (95% CI 8.7-10.7), 0.9% (95% CI 0.5-1.3), 10.4% (95% CI 9.5-11.4), and 14.8% (95% CI 13.9-15.7), respectively. Depression increased the risk of dementia up to 3.7% (95% CI 2.0-5.4), and up to 10.3% (95% CI 0.3-20.4) if coupled with diabetes complications. Eight-year mortality was 37.5% (95% CI 33.1-42.0) after depression, 74.1% (95% CI 63.7-84.5) after depression plus complications, 76.4% (95% CI 68.8-83.9) after dementia, and 98.6% (95% CI 96.1-100.0) after dementia plus complications. CONCLUSIONS: The interconnections observed across depression, dementia, complications, and mortality underscore the necessity for comprehensive and integrated approaches in managing diabetes. Early screening for depression, followed by timely and targeted interventions, may mitigate the risk of dementia and improve diabetes prognosis.

Use of machine learning to identify characteristics associated with severe hypoglycemia in older adults with type 1 diabetes: a post-hoc analysis of a case-control study.

INTRODUCTION: Severe hypoglycemia (SH) in older adults (OAs) with type 1 diabetes is associated with profound morbidity and mortality, yet its etiology can be complex and multifactorial. Enhanced tools to identify OAs who are at high risk for SH are needed. This study used machine learning to identify characteristics that distinguish those with and without recent SH, selecting from a range of demographic and clinical, behavioral and lifestyle, and neurocognitive characteristics, along with continuous glucose monitoring (CGM) measures. RESEARCH DESIGN AND METHODS: Data from a case-control study involving OAs recruited from the T1D Exchange Clinical Network were analyzed. The random forest machine learning algorithm was used to elucidate the characteristics associated with case versus control status and their relative importance. Models with successively rich characteristic sets were examined to systematically incorporate each domain of possible risk characteristics. RESULTS: Data from 191 OAs with type 1 diabetes (47.1% female, 92.1% non-Hispanic white) were analyzed. Across models, hypoglycemia unawareness was the top characteristic associated with SH history. For the model with the richest input data, the most important characteristics, in descending order, were hypoglycemia unawareness, hypoglycemia fear, coefficient of variation from CGM, % time blood glucose below 70 mg/dL, and trail making test B score. CONCLUSIONS: Machine learning may augment risk stratification for OAs by identifying key characteristics associated with SH. Prospective studies are needed to identify the predictive performance of these risk characteristics.

Female sex is a risk factor for painful diabetic peripheral neuropathy: the EURODIAB prospective diabetes complications study.

AIMS/HYPOTHESIS: While the risk factors for diabetic peripheral neuropathy (DPN) are now well recognised, the risk factors for painful DPN remain unknown. We performed analysis of the EURODIAB Prospective Complications Study data to elucidate the incidence and risk factors of painful DPN. METHODS: The EURODIAB Prospective Complications Study recruited 3250 participants with type 1 diabetes who were followed up for 7.3±0.6 (mean ± SD) years. To evaluate DPN, a standardised protocol was used, including clinical assessment, quantitative sensory testing and autonomic function tests. Painful DPN (defined as painful neuropathic symptoms in the legs in participants with confirmed DPN) was assessed at baseline and follow-up. RESULTS: At baseline, 234 (25.2%) out of 927 participants with DPN had painful DPN. At follow-up, incident DPN developed in 276 (23.5%) of 1172 participants. Of these, 41 (14.9%) had incident painful DPN. Most of the participants who developed incident painful DPN were female (73% vs 48% painless DPN p=0.003) and this remained significant after adjustment for duration of diabetes and HbA1c (OR 2.69 [95% CI 1.41, 6.23], p=0.004). The proportion of participants with macro- or microalbuminuria was lower in those with painful DPN compared with painless DPN (15% vs 34%, p=0.02), and this association remained after adjusting for HbA1c, diabetes duration and sex (p=0.03). CONCLUSIONS/INTERPRETATION: In this first prospective study to investigate the risk factors for painful DPN, we definitively demonstrate that female sex is a risk factor for painful DPN. Additionally, there is less evidence of diabetic nephropathy in incident painful, compared with painless, DPN. Thus, painful DPN is not driven by cardiometabolic factors traditionally associated with microvascular disease. Sex differences may therefore play an important role in the pathophysiology of neuropathic pain in diabetes. Future studies need to look at psychosocial, genetic and other factors in the development of painful DPN.

Risk factors of hepatocellular carcinoma in non-alcoholic fatty liver disease: a systematic review and meta-analysis.

OBJECTIVE: This study aimed to systematically review and quantitatively synthesize the existing evidence to better identify the high-risk population of hepatocellular carcinoma (HCC) in nonalcoholic fatty liver disease (NAFLD). MATERIALS AND METHODS: We searched databases including MEDLINE, EMBASE, Web of Science, Cochrane Library, and ClinicalTrials.gov up to February 2023. The meta-analysis was performed using RevMan5.3 software, and we calculated the estimated combined effect using inverse variance weighting of OR. I2 statistics were used to quantify the inter-study heterogeneity. Funnel plots and Egger test were used to assess publication bias, and sensitivity analysis was carried out through the transformation effect model or the removal of literature one by one. RESULTS: Finally, 29 articles were included in the study, which involved a total of 726,656 patients with NAFLD. A total of 15 major risk factors were evaluated. Statistically significant risk factors were: advanced liver fibrosis (OR=6.40), diabetes (OR=2.38), obesity (OR=1.46), hypertension (OR=1.75), older age (OR=3.57), male (OR=2.45), alcohol intake (OR=2.98), smoking (OR=1.44), PNPLA3 genotype variation (OR=1.76), elevated liver enzymes (OR=2.92), low platelet counts (OR=4.61), and low albumin levels (OR=2.11). CONCLUSIONS: Our results showed that advanced liver fibrosis, diabetes, obesity, hypertension, older age, male, alcohol intake, smoking, PNPLA3 genotype variation, elevated liver enzymes, low platelet counts, and low albumin levels were all significant risk factors for HCC in NAFLD. However, dyslipidemia was not found to be a risk factor. Further exploration is needed to confirm whether Hispanic ethnicity and high ferritin levels are also risk factors.

Diabetic Fibrous Mastopathy: Imaging Features With Histopathologic Correlation.

Diabetic fibrous mastopathy (DFM) is a rare benign fibrotic disease of the breast that develops in patients with longstanding and often uncontrolled diabetes mellitus. Clinically, patients may present with an irregular, firm, palpable mass, which may be solitary or multiple, occurring in one or both breasts. Diabetic fibrous mastopathy occurs most often in premenopausal women with heterogeneously or extremely dense breasts; mammography may show focal asymmetry or, less often, a noncalcified mass with indistinct or obscured margins, but there are usually no discrete findings. On US, DFM may have marked hypoechogenicity and posterior shadowing secondary to extensive fibrosis. Diabetic fibrous mastopathy features on contrast-enhanced MRI are also nonspecific, with gradual persistent nonmass enhancement reported. Because the clinical presentation and US features of DFM overlap with those of breast cancer, histopathologic correlation is needed to confirm diagnosis and exclude malignancy. These findings include collagenous stroma often with keloidal features and chronic perilobular and perivascular inflammation. Histopathologic findings of lymphocytic lobulitis and perivascular inflammation are common to other autoimmune conditions.

Effects of the ABCC8 R1420H loss-of-function variant on beta-cell function, diabetes incidence, and retinopathy.

INTRODUCTION: The ABCC8 gene regulates insulin secretion and plays a critical role in glucose homeostasis. The effects of an ABCC8 R1420H loss-of-function variant on beta-cell function, incidence of type 2 diabetes, and age-at-onset, prevalence, and progression of diabetes complications were assessed in a longitudinal study in American Indians. RESEARCH DESIGN AND METHODS: We analyzed beta-cell function through the relationship between insulin secretion and insulin sensitivity in members of this population without diabetes aged ≥5 years using standard major axis regression. We used hierarchical logistic regression models to study cross-sectional associations with diabetes complications including increased albuminuria (albumin-to-creatinine ratio (ACR) ≥30 mg/g), severe albuminuria (ACR ≥300 mg/g), reduced estimated glomerular filtration rate (eGFR <60 mL/min/1.73 m2), and retinopathy. This study included 7675 individuals (254 variant carriers) previously genotyped for the R1420H with available phenotypic data and with a median follow-up time of 13.5 years (IQR 4.5-26.8). RESULTS: Variant carriers had worse beta-cell function than non-carriers (p=0.0004; on average estimated secretion was 22% lower, in carriers), in children and adults, with no difference in insulin sensitivity (p=0.50). At any body mass index and age before 35 years, carriers had higher type 2 diabetes incidence. This variant did not associate with prevalence of increased albuminuria (OR 0.87, 95% CI 0.66 to 1.16), severe albuminuria (OR 0.96, 95% CI 0.55 to 1.68), or reduced eGFR (OR 0.44, 95% CI 0.18 to 1.06). By contrast, the variant significantly associated with higher retinopathy prevalence (OR 1.74, 95% CI 1.19 to 2.53) and this association was only partially mediated (<11%) by glycemia, duration of diabetes, risk factors of retinopathy, or insulin use. Retinopathy prevalence in carriers was higher regardless of diabetes presence. CONCLUSIONS: The ABCC8 R1420H variant is associated with increased risks of diabetes and of retinopathy, which may be partially explained by higher glycemia levels and worse beta-cell function.

Knowledge about the disease and adherence to treatment in patients with diabetes

Introduction: Glycemic decompensation in diabetes is one of the major factors for the development of chronic disease complications. Factors involved in the adequate control of diabetes include adherence to pharmacological treatment and knowledge about the disease.Methods: Cross-sectional study on the factors associated with adherence to drug treatment and knowledge about diabetes in diabetic patients treated at Hospital Universitário de Santa Maria between 2018 and 2019, based on the validated Morisky-Green test and on the Diabetes Knowledge Questionnaire.Results: A total of 201 patients diagnosed with diabetes were included, the majority (85.6%) of which had type 2 diabetes and were white (75.6%), with a mean age of 59.4 years. An association between insufficient knowledge about diabetes and patients with type 2 diabetes was observed. An association was found between patients with type 2 diabetes using insulin and non-adherence to drug treatment compared with patients with type 2 diabetes who did use insulin. The research also showed that non-adherence to drug treatment was associated with higher occurrence of hypoglycemia compared with patients who adhered to drug treatment.Conclusion: The data obtained in our study allows us to conclude that non-adherence to pharmacological treatment makes diabetes therapy more complicated and worsens the prognosis.

Avaliação imunológica promovida pelo consumo de kombucha em camundongos diabéticos / Immunologic evaluation promoted by the consumption of kombucha in diabetic mice

O kombucha é uma bebida fermentada tradicional, originária da China, preparada pela fermentação de chá preto adoçado com cultura mista de bactérias e leveduras chamada Simbiotic Culture of Bacteria and Yeast (SCOBY). Tem sido alegado que o mesmo possui propriedades funcionais, tais como recuperação ou manutenção de peso corporal, atividade antihiperglicêmica, entre outras. Por não existirem estudos suficientes que as comprovem, este trabalho teve por objetivo avaliar a influência do consumo de kombucha como tratamento alternativo para amenizar e/ou retardar sintomas e complicações do Diabetes Mellitus e identificar as possíveis modificações metabólicas, morfológicas e imunológicas ocorridas em camundongos com diabetes tipo 1. De acordo com os resultados obtidos, observou-se que, apesar de ter havido recuperação de massa corpórea próxima daquela que se tinha antes da indução da diabetes, esse efeito não foi exclusivo do kombucha e, embora a influência no controle glicêmico tenha sido maior nos camundongos normoglicêmicos que diabéticos, acredita-se que a administração por um período prolongado pudesse indicar melhores resultados, uma vez que as avaliações histológicas e morfométricas do intestino demonstraram resultados satisfatórios quanto ao aumento da superfície de mucosa e diminuição do infiltrado inflamatório, favorecendo a modulação imunológica. Logo, considera-se necessária a realização de mais trabalhos para comprovação da capacidade funcional do kombucha e elucidação de sua eficácia enquanto tratamento exclusivo e/ou complementar do diabetes

Kombucha is a traditional Chinese fermented beverage prepared by fermenting sweetened black tea with mixed bacterial and yeast culture called Simbiotic Culture of Bacteria and Yeast (SCOBY). It has been claimed that it has functional properties such as body weight recovery or maintenance, antihyperglycemic activity, among others. Because there are not enough studies to prove them, this study aimed to evaluate the influence of kombucha consumption as an alternative treatment to alleviate and/or delay symptoms and complications of Diabetes Mellitus and to identify possible metabolic, morphological and immunological changes in mice with type 1 diabetes. According to the results obtained, it was observed that, although there was a recovery of body mass close to the one obtained before diabetes induction, this effect was not unique to kombucha, and although the influence on glycemic control was greater in normoglycemic rather than diabetic mice, it is believed that administration over a prolonged period could indicate better results, since histological and morphometric evaluations of the intestine showed satisfactory results in terms of mucosal surface enlargement and decreased inflammatory infiltrate, favoring immune modulation. . Therefore, further work is considered necessary to prove the functional capacity of kombucha and to elucidate its effectiveness as an exclusive and / or complementary treatment of diabetes

Diabetes mellitus asociada a pancreatitis autoinmune: caso clínico / Autoimmune pancreatitis associated with diabetes mellitus: report of one case

Autoimmune pancreatitis is uncommon, responds to steroids and is usually associated with diabetes mellitus. We report a 73 year-old male who, two months after a diagnosis of diabetes mellitus, presented with obstructive jaundice and weight loss. Abdominal magnetic resonance imaging was suggestive of an autoimmune pancreatitis and serum IgG4 was 339 mg/dl (normal range 3-201). The patient was treated with prednisone 40 mg/day with a good clinical and laboratory response. During outpatient care, the dose of prednisone was tapered.

Associação entre a periodontite apical e o diabetes mellitus: uma revisão da literatura / Association between apical periodontitis and diabetes mellitus: a literature review

Objetivo: realizar uma revisão de literatura para verificar a relação entre o diabetes mellitus e a periodontite apical (PA). Revisão da literatura: a PA caracteriza-se por uma perda óssea na região do ápice dental, que decorre principalmente da contaminação do sistema de canais radiculares. Embora a PA seja um processo inflamatório local, na região do periápice radicular, sua progressão pode ser influenciada por patologias sistêmicas, como o diabetes. O diabetes melittus é uma patologia crônica na qual há alteração na produção de insulina ou resistência à ação desta, esse hormônio auxilia a manter a concentração normal de glicose sanguínea. O quadro de hiperglicemia crônica presente no paciente diabético descompensado ocasiona alterações fisiológicas, que permitem suspeitar de uma relação entre o diabetes e a progressão de lesões periapicais. Considerações finais: a literatura estudada sugere uma associação positiva entre a presença do diabetes e a progressão de lesões periapicais. Porém, apesar de os estudos apontarem que existe uma maior prevalência de periodontite apical em diabéticos, ainda são poucas as evidências científicas sobre o assunto. (AU)

Objective: the present study aims to review the lit-erature to verify the relationship between diabetes mellitus and apical periodontitis (AP). Literature Review: the AP is characterized by bone loss in the tooth apex region, mainly resulting from the contamination of the root canal system. Although AP is a local inflammatory process in the root peri-apex region, its development may be affected by systemic pathologies such as diabetes. Diabetes mellitus is a chronic condition that causes chang-es in insulin production or the resistance to its action, considering this hormone helps maintain-ing the normal concentration of blood glucose. The chronic hyperglycemia condition in decom-pensated diabetic patients causes physiological changes that allow establishing a relationship be-tween diabetes and the development of the peri-apical lesions. Final considerations: the literature studied suggests a positive association between the presence of diabetes and the development of periapical lesions. However, although studies in-dicate a higher prevalence of apical periodontitis in diabetics, there is still little scientific evidence on the subject. (AU)

Logistic regression analysis of clinical and computed tomography features of pulmonary abscesses and risk factors for pulmonary abscess-related empyema

OBJECTIVES: This study was conducted to investigate the risk factors for pulmonary abscess-related empyema by investigating the clinical characteristics and chest computed tomography imaging features of patients with pulmonary abscesses. METHODS: We retrospectively analyzed the chest computed tomography findings and clinical features of 101 cases of pulmonary abscess, including 25 cases with empyema (the experimental group) and 76 cases with no empyema (the control group). The potential risk factors for pulmonary abscess-related empyema were compared between the groups by using univariate and multivariate logistic regression analyses. RESULTS: The incidence of pulmonary abscess-related empyema was 24.8% (25/101). Univariate analysis showed that male gender, diabetes, pleuritic symptoms, white blood cells >10×109/L, albumin level <25 g/L, and positive sputum cultures were potential clinical-related risk factors and that an abscess >5 cm in diameter and transpulmonary fissure abscesses were potential computed tomography imaging-related risk factors for pulmonary abscess-related empyema. Multivariate logistic regression analysis showed that transpulmonary fissure abscesses (odds ratio=9.102, p=0.003), diabetes (odds ratio=9.066, p=0.003), an abscess >5 cm in diameter (odds ratio=8.998, p=0.002), and pleuritic symptoms (odds ratio=5.395, p=0.015) were independent risk factors for pulmonary abscess-related empyema. CONCLUSIONS: Transpulmonary fissure abscesses, diabetes, giant pulmonary abscesses, and pleuritic symptoms increased the risk of empyema among patients with pulmonary abscesses.

An umbrella review on the effects of diabetes on implant failure and peri-implant diseases

Abstract The aim of this review is to summarize the evidence on associations between diabetes mellitus (DM) and complications around dental implants. Electronic database searches of MEDLINE, EMBASE, JBI Database of Systematic Reviews and Implementation Reports, Cochrane Database of Systematic Reviews and the PROSPERO register were performed from 1990 up to and including May 2018, using MeSH terms and other keywords. Systematic reviews and meta-analyses investigating the associations of DM and implant complications (failure, survival, bone loss, peri-implant diseases, and post-surgery infection) were eligible. The quality of the included reviews was determined using the Assessment of Multiple Systematic Reviews Tool 2 (AMSTAR 2). Twelve systematic reviews were included. Implant survival rates ranged from 83.5% to 100%, while implant failure rates varied from 0% to 14.3% for subjects with DM. The three meta-analyses performed for event "implant failure" reported no statistically significant differences between diabetic and non-diabetic subjects. An apparently increased risk of peri-implantitis is reported in patients with DM. According to the AMSTAR 2 classification, 50% of the reviews were classified as being of "critically low", 25% as of "low" and 25% as of "moderate" quality. Evidence indicates high levels of survival and low levels of failure of implants inserted in patients with DM. However, DM was assessed as a whole in the majority of studies and, the actual influence of hyperglycemia on implant survival/failure is still uncertain. DM/hyperglycemia seems to be associated with a high risk of peri-implantitis. However, this conclusion is based on a limited number of systematic reviews.

Effects of diabetes mellitus and systemic arterial hypertension on elderly patients' hearing / Effects of diabetes mellitus and systemic arterial hypertension on elderly patients' hearing

Abstract Introduction: Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. Objective: To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. Methods: 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. Results: When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4 kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2 kHz, 3 kHz and 8 kHz. Conclusion: It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions, hypertension seems to have the greatest influence on hearing.

Resumo: Introdução: Doenças crônicas podem atuar como fator de aceleração na degeneração do sistema auditivo. Os estudos sobre a associação da presbiacusia com o diabetes mellitus e com a hipertensão arterial sistêmica mostraram conclusões controversas. Objetivo: Comparar a audiometria inicial (A1) com uma audiometria sequencial (A2) feita com um intervalo de três a quatro anos em uma população de idosos portadores de diabetes mellitus e/ou hipertensão arterial sistêmica, a fim de saber se a perda de acuidade auditiva nesses grupos é mais acelerada comparados com controles sem essas condições clínicas. Método: Participaram deste estudo 100 idosos. Para a análise dos limiares auditivos, foram usadas: uma avaliação audiológica completa feita anteriormente (A1) e uma nova avaliação audiológica (A2) feita após três a quatro anos da primeira. Os participantes foram distribuídos em quatro grupos: 20 indivíduos no grupo com diabetes mellitus, 20 no grupo hipertensão arterial sistêmica, 20 no grupo diabetes mellitus/hipertensão arterial sistêmica e 40 indivíduos no grupo controle, foram pareados com cada grupo de estudo, de acordo com as características referentes a idade e sexo. Foram usados os testes estatísticos Anova e Kruskal-Wallis, com nível de significância de 0,05. Resultados: Na comparação da média de aumento anual dos limiares auditivos da avaliação A1 com a avaliação A2, considerando cada grupo estudo e seu respectivo controle, pode-se observar que para o grupo diabetes mellitus não houve diferença estatisticamente significante para qualquer das frequências; para o grupo hipertensão arterial sistêmica foram observadas diferenças significantes a partir de 4 kHz. Já para o grupo diabetes mellitus/hipertensão arterial sistêmica foram observadas diferenças significantes nas frequências de 500, 2k, 3k e 8 kHz. Conclusão: Verificou-se que o grupo hipertensão arterial sistêmica foi o que apresentou maior queda dos limiares auditivos no segmento estudado, quando comparado com os outros grupos, sugeriu que entre as três condições estudadas a hipertensão parece ser a que teve maior influência sobre a audição.

The Prognostic Value and Clinical Use of Myocardial Perfusion Scintigraphy in Asymptomatic Patients after Percutaneous Coronary Intervention / O Valor Prognóstico e o uso Clínico da Cintilografia de Perfusão Miocárdica em Pacientes Assintomáticos após Intervenção Coronariana Percutânea

Abstract Background: The role of myocardial perfusion scintigraphy (MPS) in the follow-up of asymptomatic patients after percutaneous coronary intervention (PCI) is not established. Objectives: To evaluate the prognostic value and clinical use of MPS in asymptomatic patients after PCI. Methods: Patients who underwent MPS consecutively between 2008 and 2012 after PCI were selected. The MPS were classified as normal and abnormal, the perfusion scores, summed stress score (SSS), and summed difference score (SDS) were calculated and converted into percentage of total perfusion defect and ischemic defect. The follow-up was undertaken through telephone interviews and consultation with the Mortality Information System. Primary endpoints were death, cardiovascular death, and nonfatal acute myocardial infarction (AMI), and secondary endpoint was revascularization. Logistic regression and COX method were used to identify the predictors of events, and the value of p < 0.05 was considered statistically significant. Results: A total of 647 patients were followed for 5.2 ± 1.6 years. 47% of MPS were normal, 30% were abnormal with ischemia, and 23% were abnormal without ischemia. There were 61 deaths, 27 being cardiovascular, 19 non-fatal AMI, and 139 revascularizations. The annual death rate was higher in those with abnormal perfusion without ischemia compared to the groups with ischemia and normal perfusion (3.3% × 2% × 1.2%, p = 0.021). The annual revascularization rate was 10.3% in the ischemia group, 3.7% in those with normal MPS, and 3% in those with abnormal MPS without ischemia. The independent predictors of mortality and revascularization were, respectively, total perfusion defect greater than 6%, and ischemic defect greater than 3%. Forty-two percent of the patients underwent MPS less than 2 years after PCI, and no significant differences were observed in relation to those who underwent it after that period. Conclusion: Although this information is not contemplated in guidelines, in this study MPS was able to predict events in asymptomatic after PCI patients, regardless of when they were performed.

Resumo Fundamentos: O papel da cintilografia de perfusão miocárdica (CPM) no seguimento de pacientes assintomáticos após intervenção coronariana percutânea (ICP) não está estabelecido. Objetivos. Avaliar o valor prognóstico e o uso clínico da CPM em pacientes assintomáticos após ICP. Métodos: Foram selecionados pacientes que realizaram CPM consecutivamente entre 2008 e 2012 após ICP. As CPM foram classificadas em normais e anormais, os escores de perfusão, escore somado do estresse (SSS) e escore somado da diferença (SDS) foram calculados e convertidos em porcentagem de defeito perfusional total e de defeito isquêmico. O seguimento foi por meio de entrevistas telefônicas e consulta ao Sistema de Informação de Mortalidade. Desfechos primários foram morte, morte cardiovascular e infarto agudo do miocárdio (IAM) não fatal e desfecho secundário foi revascularização. Regressão logística e método de COX foram utilizados para identificar os preditores de eventos e o valor de p < 0,05 foi considerado estatisticamente significativo. Resultados: 647 pacientes foram acompanhados por 5,2 ± 1,6 anos. 47% das CPM foram normais, 30% anormais com isquemia e 23% anormais sem isquemia. Ocorreram 61 mortes, 27 cardiovasculares, 19 IAM não fatais e 139 revascularizações. A taxa anual de óbitos foi superior naqueles com perfusão anormal sem isquemia comparada aos grupos com isquemia e perfusão normal (3,3% × 2% × 1,2%, p = 0,021). A taxa anual de revascularização foi 10,3% no grupo com isquemia, 3,7% naqueles com CPM normal e 3% naqueles com CPM anormal sem isquemia. Foram preditores independentes de mortalidade e revascularização, respectivamente, defeito perfusional total maior que 6% e defeito isquêmico maior que 3%. Quarenta e dois por cento dos pacientes realizaram CPM menos de 2 anos após ICP e não foram observadas diferenças relevantes em relação aos que realizaram após esse período. Conclusão: Embora esta informação não esteja contemplada em diretrizes, neste estudo a CPM foi capaz de predizer eventos em pacientes assintomáticos após ICP, independente do momento de realização.

Gender-Based Differences in Anxiety and Depression Following Acute Myocardial Infarction / Diferenças por Sexo na Ansiedade e Depressão após Infarto Agudo do Miocárdio

Abstract Background: Among patients with heart disease, depression and anxiety disorders are highly prevalent and persistent. Both depression and anxiety play a significant role in cardiovascular disease progression and are acknowledged to be independent risk factors. However, there is very little gender-related analysis concerning cardiovascular diseases and emotional disorders. Objective: We aimed to evaluate depression and anxiety levels in patients suffering from myocardial infarction [MI] within the first month after the MI and to assess the association between cardiovascular disease risk factors, demographic indicators and emotional disorders, as well as to determine whether there are gender-based differences or similarities. Methods: This survey included demographic questions, clinical characteristics, questions about cardiovascular disease risk factors and the use of the Hospital Anxiety and Depression Scale [HADS]. All statistical tests were two-sided, and p values < 0.05 were considered statistically significant. Results: It was determined that 71.4% of female and 60.4% of male patients had concomitant anxiety and/or depression symptomatology (p = 0.006). Using men as the reference point, women had an elevated risk of having some type of psychiatric disorder (odds ratio, 2.86, p = 0.007). The HADS-D score was notably higher in women (8.66 ± 3.717) than men (6.87 ± 4.531, p = 0.004). It was determined that male patients who developed depression were on average younger than those without depression (p = 0.005). Conclusions: Women demonstrated an elevated risk of having anxiety and/or depression disorder compared to men. Furthermore, depression severity increased with age in men, while anxiety severity decreased. In contrast, depression and anxiety severity was similar for women of all ages after the MI. A higher depression score was associated with diabetes and physical inactivity, whereas a higher anxiety score was associated with smoking in men. Hypercholesterolemia was associated with both higher anxiety and depression scores, and a higher depression score was associated with physical inactivity in women.

Resumo Fundamento: Os pacientes com doença cardíaca, depressão e transtornos de ansiedade são altamente prevalentes e persistentes. A depressão e a ansiedade desempenham um papel significativo na progressão da doença cardiovascular e são reconhecidas como fatores de risco independentes. No entanto, há muito pouca análise relacionada ao gênero em relação às doenças cardiovasculares e transtornos emocionais. Objetivo: Avaliar os níveis de depressão e ansiedade em pacientes com infarto do miocárdio (IM) no primeiro mês após o IM e avaliar a relação entre os fatores de risco para doença cardiovascular, indicadores demográficos e distúrbios emocionais, bem como determinar se existem diferenças ou semelhanças baseadas no sexo do paciente. Métodos: Esta pesquisa incluiu questões demográficas, características clínicas, questões sobre fatores de risco de doença cardiovascular e a Escala Hospitalar de Ansiedade e Depressão [HADS]. Todos os testes estatísticos foram bilaterais, e valores de p < 0,05 foram considerados estatisticamente significativos. Resultados: Determinou-se que 71,4% dos pacientes do sexo feminino e 60,4% dos pacientes do sexo masculino apresentavam sintomatologia concomitante de ansiedade e/ou depressão (p = 0,006). Utilizando os homens como o ponto de referência, as mulheres mostraram um risco elevado de apresentar qualquer distúrbio psiquiátrico (odds ratio, 2,86, p = 0,007). O escore da HADS-D foi notavelmente maior nas mulheres (8,66 ± 3,717) do que nos homens (6,87 ± 4,531, p = 0,004). Foi determinado que os pacientes do sexo masculino que desenvolveram depressão eram em média mais jovens do que aqueles sem depressão (p = 0,005). Conclusões: As mulheres demonstraram risco mais elevado de apresentar distúrbio de ansiedade e/ou depressão em comparação aos homens. Além disso, a gravidade da depressão aumentou com a idade entre os homens, enquanto o gravidade da ansiedade diminuiu. Em contraste, a gravidade da depressão e ansiedade foram semelhantes para mulheres de todas as idades após o IM. Um maior escore de depressão foi associado com diabetes e inatividade física, e o maior escore de ansiedade foi associado ao tabagismo nos homens. A hipercolesterolemia foi associada tanto aos maiores escores de ansiedade e depressão, enquanto um maior escore de depressão foi associado à inatividade física entre mulheres.

Dietary intake of non-dialysis chronic kidney disease patients: the PROGREDIR study. A cross-sectional study

ABSTRACT BACKGROUND: Despite evidence that diet is very important in relation to chronic kidney disease (CKD) progression, studies in this field are scarce and have focused only on some specific nutrients. We evaluated the energy, macronutrient and micronutrient intakes and dietary patterns of non-dialysis CKD participants in the PROGREDIR study. DESIGN AND SETTING: Cross-sectional study; CKD cohort, São Paulo, Brazil. METHODS: Baseline data on 454 participants in the PROGREDIR study were analyzed. Dietary intake was evaluated through a food frequency questionnaire. Dietary patterns were derived through principal component analysis. Energy and protein intakes were compared with National Kidney Foundation recommendations. Linear regression analysis was performed between energy and nutrient intakes and estimated glomerular filtration rate (eGFR), and between sociodemographic and clinical variables and dietary patterns. RESULTS: Median energy and protein intakes were 25.0 kcal/kg and 1.1 g/kg, respectively. In linear regression, protein intake (β = -3.67; P = 0.07) was related to eGFR. Three dietary patterns (snack, mixed and traditional) were retained. The snack pattern was directly associated with male gender (β = 0.27; P = 0.006) and inversely with diabetes (β = -0.23; P = 0.02). The traditional pattern was directly associated with male gender (β = 0.27; P = 0.007) and schooling (β = 0.40; P < 0.001) and inversely with age (β = -0.01; P = 0.001) and hypertension (β = -0.34; P = 0.05). CONCLUSIONS: We identified low energy and high protein intake in this population. Protein intake was inversely related to eGFR. Dietary patterns were associated with age, gender, schooling level, hypertension and diabetes.
