Assessment of frailty in the person with type 2 diabetes mellitus: Expert analysis.

INTRODUCTION: People with type 2 diabetes mellitus (DM2) have a higher prevalence of frailty compared to those without DM2. However, there is a lack of consensus on the diagnosis and clinical management of frail individuals with DM2. OBJECTIVES: This study aims to identify limitations and current needs in the use of the frailty concept in PCDM2 (people with DM2), as well as define and evaluate the dimensions that should be included in its routine clinical assessment. METHODS: A multidisciplinary team of eight health professionals from different hospitals in Spain participated in a process based on the nominal group technique. RESULTS: The study identified eight limitations in the assessment of frailty in PCDM2, categorized by importance, and 10 unmet needs related to the diagnosis and follow-up of the disease. Additionally, seven dimensions were identified that should be included in the definition of frail individuals with DM2, prioritized by importance and novelty. CONCLUSIONS: This article aims to increase knowledge and usage of the frailty concept in individuals with DM2 within the medical community. It also suggests the potential for future projects to develop a consensus definition of frailty tailored to this specific group.

Executive summary on the treatment of type 2 diabetes mellitus in elderly or frail individuals. 2022 update of the 2018 consensus document "Treatment of type 2 diabetes mellitus in the elderly".

The population with type 2 DM (DM2) is highly heterogeneous, representing an important challenge for healthcare professionals. The therapeutic choice should be individualized, considering the functional status, frailty, the occurrence of comorbidities, and the preferences of patients and their caregivers. New evidence on the cardiovascular and renal protection of specific therapeutic groups and on the usefulness of new technologies for DM2 management, among other aspects, warrant an update of the consensus document on the DM2 in the elderly that was published in 2018.

[Tuberculous peritonitis in peritoneal dialysis]. / Peritonitis tuberculosa en diálisis peritoneal.

We report a patient in Automatic Peritoneal Dialysis (APD) with tuberculous peritonitis by possible peritoneal infection due to the proximity between fallopian tube and the left ovary, a peritoneal liquid culture was constantly negative. The patient presented a bad clinic evolution. Her only medical history was hypercalcemia six months before developing a peritonitis and occasionally nausea and vomits To confirm the diagnosis it was needed a peritoneal biopsy by means of a laparoscopy with a removal of the peritoneal catheter and left anexectomy. Now, the patient is asintomatic in daily home hemodialysis.

[Prevention and treatment of infectious diseases in diabetic patients]. / Prevención y tratamiento de la enfermedad infecciosa en personas con diabetes.

The bidirectional relationship between infectious diseases and diabetes is well-known. On the one hand, diabetes patients are at a higher risk of presenting with infectious diseases, possibly with more severity, and on the other hand, infectious diseases impair metabolic control in patients with diabetes. Population ageing arises partly due to an increased survival rate in chronic diseases, of which diabetes is amongst them. Improving infectious disease prevention could reduce complications arising from the former diseases, consequences of decompensated diabetes condition (morbidity, incapacity, hospital admissions, healthcare costs, and mortality rates) and result in improved quality of life in patients with diabetes. The current review presents the treatment of infectious diseases in patients with diabetes and the dealing with immuno-preventable diseases with the currently advised vaccinations.

Treatment of type 2 diabetes mellitus in elderly patients. / Tratamiento de la diabetes mellitus tipo 2 en el paciente anciano.

The prevalence of type 2 diabetes mellitus (DM2) increases markedly with age. Antidiabetic treatment and the objectives of glycaemic control in elderly patients with DM2 should be individualised according to their biopsychosocial characteristics. In elderly patients for whom the benefits of intensive antidiabetic treatment are limited, the basic objectives should be to improve the quality of life, preserve functionality and avoid adverse effects, especially hypoglycaemia. Treatment of DM2 in the elderly was the subject of a consensus document published in 2012 and endorsed by several Spanish scientific societies. Since then, new therapeutic groups and evidence have emerged that warrant an update to this consensus document. The present document focuses on the therapeutic aspects of DM2 in elderly patients, understood as being older than 75 years or frail.

Hyperspectral data processing improves PpIX contrast during fluorescence guided surgery of human brain tumors.

Fluorescence guided surgery (FGS) using aminolevulinic-acid (ALA) induced protoporphyrin IX (PpIX) provides intraoperative visual contrast between normal and malignant tissue during resection of high grade gliomas. However, maps of the PpIX biodistribution within the surgical field based on either visual perception or the raw fluorescence emissions can be masked by background signals or distorted by variations in tissue optical properties. This study evaluates the impact of algorithmic processing of hyperspectral imaging acquisitions on the sensitivity and contrast of PpIX maps. Measurements in tissue-simulating phantoms showed that (I) spectral fitting enhanced PpIX sensitivity compared with visible or integrated fluorescence, (II) confidence-filtering automatically determined the lower limit of detection based on the strength of the PpIX spectral signature in the collected emission spectrum (0.014-0.041 µg/ml in phantoms), and (III) optical-property corrected PpIX estimates were more highly correlated with independent probe measurements (r = 0.98) than with spectral fitting alone (r = 0.91) or integrated fluorescence (r = 0.82). Application to in vivo case examples from clinical neurosurgeries revealed changes to the localization and contrast of PpIX maps, making concentrations accessible that were not visually apparent. Adoption of these methods has the potential to maintain sensitive and accurate visualization of PpIX contrast over the course of surgery.

[Methodological aspects of integrated care pathways]. / Aspectos metodológicos de los procesos asistenciales integrados (PAI).

An Integrated Healthcare Pathway (PAI) is a tool which has as its aim to increase the effectiveness of clinical performance through greater coordination and to ensure continuity of care. PAI places the patient as the central focus of the organisation of health services. It is defined as the set of activities carried out by the health care providers in order to increase the level of health and satisfaction of the population receiving services. The development of a PAI requires the analysis of the flow of activities, the inter-relationships between professionals and care teams, and patient expectations. The methodology for the development of a PAI is presented and discussed in this article, as well as the success factors for its definition and its effective implementation. It also explains, as an example, the recent PAI for Hypoglycaemia in patients with Type 2 Diabetes Mellitus developed by a multidisciplinary team and supported by several scientific societies.

Sealant and fluoride varnish in caries: a randomized trial.

Little is known about the effect of discontinuation of sealant or fluoride varnish. The purpose of this study was to compare sealant with fluoride varnish in the prevention of occlusal caries in permanent first molars of children over a nine-year period: 4 yrs for program evaluation plus 5 yrs of discontinuation. A clinical trial was conducted on three groups of six- to eight-year-old schoolchildren: a control group (n = 45); a group (n = 37) in which sealant was applied and reapplied up to 36 mos; and a group (n = 38) in which fluoride varnish was applied and re-applied up to 42 mos. Percent caries reduction was studied in these initially healthy molars with complete occlusal eruption: 129 (control), 113 (sealant), and 129 (varnish) molars met inclusion criteria. Of these, 76.7%, 26.6%, and 55.8% had developed occlusal caries at 9 yrs, which implies caries reductions of 65.4% (SE = 8.5%) for sealants vs. control and 27.3% (SE = 10.2%) for varnish vs. control. Furthermore, the varnish program was not effective during the discontinuation period.

Adhesion molecule CD44 as a prognostic factor in laryngeal cancer.

BACKGROUND: Loss of expression of CD44 has been shown to be a factor of poor prognosis in some types of tumors. The purpose of this study was to analyze this event in relation to the survival of patients with laryngeal cancer. PATIENTS AND METHODS: The expression of adhesion molecule CD44 was studied in 137 patients with laryngeal cancer. Data were gathered on clinical (primary tumor location, pyriform sinus involvement and tongue base damage) and pathologic (T, N, differentiation, inflammatory response, tumor thickness, surgical margin involvement, and CD44 expression) parameters. Immunohistochemical studies were carried out using DF1485 anti-CD44 monoclonal antibody. RESULTS: In 29 tumors (21.1%) < 25%, in 18 (13.1%) 25%-49%, in 42 (30.6%) 50%-74%, and in 48 (35.0%) > or = 75% of the neoplastic cells expressed CD44. A Cox proportional risks multivariate analysis identified CD44 expression and surgical margin involvement as the parameters most associated with survival (p<0.001). CONCLUSION: The reduced expression of CD44 behaves as a marker of a poor laryngeal cancer prognosis.

[Behaviour of vancomycin with the new techniques in haemodialysis]. / Comportamiento de la vancomicina con tas nuevas técnicas de diálisis.

UNLABELLED: When using high convection dialysis techniques it arouses the necessity of considering the suitability of the regular protocols when administrating drugs, such as vancomycin. OBJECTIVES: To confirm if the usual guideline of vancomycin is efficient in patients undergoing treatments with acetate free biofiltration (AFB) and haemodiafiltration on-line (on-line). To propose an alternative guideline of administration. MATERIAL AND METHODS: 13 patients treated with AFB or On-line. 10 of them used filters of polysulfone and 3 of them of AN69. First part: 6 patients were administered 1 g iv during the last hour of dialysis. Second part: 7 patients were given a loading dose of 30 mg/kg iv with a reinforcement of 500 mg post-dialysis. The blood levels of the antibiotic were monitorized during the week following the administration. OUTCOMES: During the first phase it was noticed a decrease of 41% in the serum level of vancomycin during dialysis, conditioning subtherapeutic levels in the 83% of the patients until the end of the study. As for the second phase, therapeutic non-toxic levels were maintained during the whole study. The existence of a post-dialysis rebound of the 21 % was confirmed. A bigger clearance of vancomycin was obtained with the On-line technique rather than with AFB (176 vs 135 ml/min). We find a strong correlation between the decrease of the antibiotic and the volume ultrafiltrated with the On-line technique. CONCLUSIONS: The usual guideline of vancomycin may not be enough with the new convective dialysis techniques. A guideline based on a loading dose of 30 mg/kg and a reinforcement of 500 mg at the end of each dialysis could be adequate. The antibiotic clearance with the On-line technique is probably made by convective transport.

[Blood pressure control in a population of hypertensive diabetic patients treated in primary care: PRESCAP-Diabetes Study 2010]. / Control de la presión arterial en una población hipertensa diabética asistida en atención primaria: Estudio PRESCAP-Diabetes 2010.

OBJECTIVES: To determine the level of blood pressure (BP) control in hypertensive diabetic patients treated in primary care and to determine the factors associated with poor control. MATERIAL AND METHODS: A cross-sectional, multicentre study that enrolled hypertensive diabetics recruited by consecutive sampling by family doctors in Spain in June 2010. A mean BP of less than 140/90mmHg was considered as good control of arterial hypertension. The percentages of patients with<130/80mmHg PA, 140/80mmHg, and 140/85mmHg, respectively, were also determined. Sociodemographic, clinical, cardiovascular risk factors, and pharmacological treatments were recorded. RESULTS: A total of 3,993 patients were enrolled (50.1% female) with a mean age (standard deviation) of 68.2 (10.2) years, of whom 73.9% received combination therapy. The figures showed good control of both blood pressure values (<140/90mmHg) in 56.4% (95% CI: 54.3 to 58.4) of the cases, with 58.5% (95% CI: 57.0-60.0) only in systolic BP, and 84.6% (95% CI, 83.2 to 85.8) only in diastolic BP. The variables with strongest association with poor control were the presence of albuminuria, elevated total cholesterol, physical inactivity, and not taking the medication on the day of the interview. CONCLUSIONS: The PRESCAP-Diabetes 2010 study results indicate that 43.6% of diabetics with hypertension seen in primary care have a poorly controlled BP, in particular, systolic BP.

[Consensus document on the treatment of dyslipidemia in diabetes]. / Recomendaciones de buena práctica en el tratamiento de la dislipemia en la diabetes.

People with type 2 diabetes mellitus have a 2 to 4 times higher risk of developing cardiovascular diseases when compared to general population of similar age and sex. This risk remains after adjustment of other traditional cardiovascular risk factors. The dyslipidemia associated with type 2 diabetes mellitus is present in up to 60% of people with diabetes and contributes greatly to increased cardiovascular, morbidity and mortality risk in these patients. Diabetic dyslipidemia is a disorder of lipid metabolism characterized by an excess of triglycerides, a decrease in HDL-cholesterol and altered lipoprotein composition, consisting mainly in an excess of small, dense LDL particles. Multiple clinical trials have demonstrated the benefits of drug treatment of dyslipidemia (mainly statins) to prevent cardiovascular events and mortality in people with diabetes, both in primary and secondary prevention. This consensus document, developed by general practitioners, members of the Diabetes Group of the Spanish Society of Primary Care Physicians (SEMERGEN), aims to assist in the management of patients with diabetes and dyslipidemia in accordance with the most recent recommendations.

Obesity and excess weight are the main preventable causes of type 2 diabetes (DM2). When diagnosing type 2 diabetes, clinicians should establish the degree of obesity according to the body mass index (BMI) and, for patients with excess weight, measure the waist circumference. The proper treatment of DM2 requires a simultaneous approach to excess weight/obesity and the other cardiovascular risk factors, such as hypertension, dyslipidaemia and smoking. Nondrug interventions (e.g., diet and exercise) have proven benefits in preventing and treating patients with DM2 and excess weight/obesity and should follow an individual and multidisciplinary approach, with structured programs equipped with specific resources. Weight gain associated with antidiabetic treatment can hinder glycaemic control, compromise treatment adherence, worsen the vascular risk profile and limit the cardiovascular benefits of treatment. Therefore, it is significant to avoid weight gain, a measure that can be cost-effective. Antidiabetic drugs with benefits in body weight have also demonstrated their benefit in patients with BMIs <30. In general, the treatment of patients with DM2 and obesity will depend both on the degree of obesity and the associated comorbidity. Clinical trials on DM2 intervention should consider combined objectives that include not only glycaemic control but also other variables such as the risk of hypoglycaemia and the effect of treatment on body weight.

Arterial embolization: problems of source, multiplicity, recurrence, and delayed treatment.

The clinical course of 225 patients who had experienced 309 arterial embolic episodes was reviewed with special reference to the problems of the identification of the source of embolization, multiplicity of involvement, significance of recurrence, and the effects of some therapeutic means, including anticoagulation, on the early and late results. The most common source of embolization was cardiac (in 85% of the cases). Persistent search, at times by complex diagnostic methods, uncovered the origin in all but 11% of the cases. Within a range of 8 hours to 7 days the effect of delayed treatment had a linear relationship to the severity of ischemic changes and the deterioration of favorable results. Angiography was helpful and often essential in the diagnosis of visceral embolism and in differentiating local thrombosis from embolism in the periphery. Recurrent embolization was common (in 28% of the cases), was often multiple, and had a grave prognosis. Permanent anticoagulant therapy, preferably with but even without the removal of the source of embolization, reduced the rate of recurrence and, in general, reduced early and late morbidity and mortality rates.

[Contributions of SGLT-2 and new drugs under investigation]. / Aportaciones de los SGLT-2 y nuevos fármacos en investigación.

DeFronzo spoke of the "ominous octet", in which he referred to the existence of distinct pathways and organs related to the physiopathology of type 2 diabetes mellitus (DM2). One of these key organs is the kidney, which plays an important role in regulating glucose metabolism through gluconeogenesis and through glomerular filtration and glucose reabsorption in the proximal convoluted tubules. Approximately 180 g of glucose are filtered to the renal tubule from the blood stream through the glomerulus. The filtrate is subsequently reabsorbed from the tubules to the peritubular capillaries through the action of sodium glucose cotransporters (SGLT). There are 2 main cotransporters in the kidney, SGLT1 and SGLT2, which reabsorb the glucose (10% and 90%, respectively) and return it to the blood. In persons with DM2, SGLT2 is increased, leading to greater renal absorption of glucose, which has adverse effects as it contributes to the maintenance of hyperglycemia. Selective pharmacological SGLT2 inhibition increases renal glucose excretion and secondarily reduces its plasma values. SGLT2 inhibitors act exclusively on the kidney, reduce glycosylated hemoglobin (HbA1c) by about 0.66%, decrease blood pressure, and induce a weight loss of approximately 1.8 kg. These drugs have a low risk of hypoglycemia but carry an increased risk of genitourinary infections. Several clinical trials have shown that dapagliflozin (10mg/day), the first SGLT2 inhibitor commercialized in Spain, produces a statistically significant reduction in HbA1c of 0.82-0.97%, both in monotherapy and in combination with metformin, glimepiride, pioglitazone, or insulin. Its use produces a weight loss of between 2 and 3 kg and reduces both systolic and diastolic blood pressure, while the risk of hypoglycemias is low.

Treatment of juxtafoveal and parafoveal neovascular membranes with monochromatic green argon photocoagulation: green laser.

Sixty eyes in 58 patients with either juxtafoveal or parafoveal neovascular membranes were treated with monochromatic green argon photocoagulation. The visual acuity was stabilized or improved in 73.2% (22 eyes) in both the juxtafoveal and parafoveal groups. Total eradication of the neovascular membranes was possible in 86.6% (26 eyes) in the juxtafoveal group and 93.4% (28 eyes) of the parafoveal group. This study suggests that successful treatment of both juxtafoveal and parafoveal neovascular membranes can be accomplished with monochromatic green argon photocoagulation.
